NI SoftwareLabView Communications System Design Suite 1.1LTE Application Framework 1.1Windows 7 Enterprise NI HardwareUSRP RIO 2943RUSRP RIO 2953RDriver: NI-RIO 15.0 Problem Description On Monday 29.2 I run the DL operation mode of the LTE Application Framework using the single device configuration (just one USRP RIO 2943, connected through a PCIe x4 module to a desktop Win7 computer) and I got the following error message: I can not find a reasonable explanation for this since I am running the program directly "out of the box", the bitfile is pre-compiled from factory and I did not touch anything in the files. Furthermore, one month ago I was able to run it with no problem, using exactly the same device, cables and connectors. Here is a screenshot of the erroneous code: As you can see, the .lvbitx file (pre-compiled from factory) for the DL operation mode is being deployed. Troubleshooting process First round of adjustments:Update all the pending updates of Windows 7Look for critical updates via NI Update Service (nothing was listed)Look for optional updates via NI Update Service (I installed all the ones listed but "FlexRIO 15.0" which I felt useless)Re-run the LabView Communications installer in case something needed to be reinstalledAfter these, I tried to run the program again and still the error is popping up. In order check if this is a problem of the LTE App framework, I run the FM demodulator tutorial for USRP and this one worked, so I am afraid that there is some issue in the LTE App framework that escapes my understanding. Second round of adjustments:I uninstalled every single software of NI and installed everything again.I tried to compile the bitfile my myself but I got an error regarding the license I am using (I am still using the one for students provided to KTH). I am attaching the logfile that the compilation process outputs.I have tried connecting the USRP RIO 2953RI have updated to LabView Runtime 2015 f2I have installed NI-VISA Runtime 15.0I have installed the FPGA Interface C API Generator 15.0 as this post recommended (even when I think it is not applicable in my case) http://forums.ni.com/t5/LabVIEW/Error-63101-when-running-FPGA-Interface-C-API-Generator-in/td-p/2162...I have updated my Window 7 with the latest updates available in the Windows Updates Center. Nothing has worked so far. Here you can find screenshots of MAX and the NI License Manager in case they are also useful: Does anyone have any idea of what could be wrong in here? Thanks in advance,Adrian

SOLVED

I am seriously thinking about hanging up myself after figuring out what the problem was.

One month ago I started saving my projects directly into a Dropbox folder. Dropbox software seems to have been doing something to the files that have been saved on it in a way that LabView Communications was complaining all the time about the .lvbitx file as described by error -63101.

SOLUTION: save your files in your computer or even in your USB memory stick, but do not use anything like Dropbox, OneDrive or Google Drive since they and LabView Communications seem not to hit it off.
