Civil 3D (2016) Traverse Adjustments and .FBK files

Hello all, I've been lurking around here for a while, first time posting here. 

I've been at my new company for just a hair over five months now and I find myself banging my head against the wall all the time trying to get the hang of using Civil3D 2016.  It never seems to end, I know a lot of people say it's just someones unwillingness to learn how to really use Civil3D, personally I think it is far less intuitive than Carlson, which is where my experience lies, I'm not looking for a debate, I'm just trying to learn how to use the software I'm provided.  I've wasted a phenomenal amount of time trying to figure out how to even analyze a traverse loop our field crew has run recently, much less adjust it. 

From what I'm reading as well as multiple tutorials I've come across, the best way to do this seems to be exporting a .fbk file from our field crew's Topcon FC5000 data collector with Magnet Field and then importing said .fbk file into a new drawing file as a standard import event.  In fairness, this is the first time I have used .fbk files, but each and every time I do this I get some sort of error, something along the lines of  "(insert file name) Line 37  Error: Direction already exists." Like I said, fieldbook files are new to me, so I may not know exactly what I'm looking for, but I'm not personally seeing anything that stands out in said file as a problem.

I spent years manually entering angles and distances into notepad to create a batch file to run through COGOPC software from the late '80s, and then running compass adjustments on traverse, this stuff has me stumped and the help menu and error messages are utterly useless.  No one currently at this company has done a traverse adjustment in nearly a decade or more, so they've been of no help with this stuff.  Does anyone have any tips or tricks? Can someone tell me what I'm missing?? The website won't let me upload the .fbk file, but I'm including a .txt version of it.

Thanks in advance, any help would be a godsend at this point.

I started with Softdesk in 1997 and have graduated from than to LDD, and now to C3d. I've worked 6 different jobs in that time, in 3 states.  I've worked with dozens of surveyors and technicians in that time, who themselves came from the 4 corners of the survey universe.  Not one of them ever tried to adjust their  traverses using fdk and Softdesk/LDD/C3d. 

I have posted questions very much like yours to this board over the years and have had people insist that it can be done, and that they do it regularly. But I have never seen it done. The fact that your post has been up for nearly a full day with no response says something.

I use StarNet. My many employers have always been willing to buy it for me if they didn't have it already (except one case where they were using LGO for the same purpose).

Civil 3d is a pretty good design piece of software (I use it everyday for civil engineering projects).

It is a pretty poor survey piece of software.  Everyone I know, no matter the firm, uses an exterior adjustment software and usually uses Civil3d for the field-to-finish (if they use Civil 3D at all, that is).

Civil3d is not a friendly to traverse adjustments. I think i used it once 5 years ago. It can be done, it just requires a very specifically structured set of data.

Any adjustments should be made prior to introducing the data to Civil3d.  Most use StarNet or TBC for adjustments.

I'll admit, these are exactly the responses I was expecting prior to posting, thank you all for confirming this.  I truly think that the surveying side of Civil 3d was an afterthought. 

I essentially made the same post on Autodesk's own forum and have only gotten a single response, from another user, which has been of no help at all.
