Visual Studio 2010 Shell Error - is it Causing this SQL Server error?

Visual Studio 2010 Isolated Shell has the infamous "Invalid License Data. Reinstall" error. I have SSMS 2014. I have tried reinstalling several times, I installed Visual Studio 2013 but SSMS doesn't recognize it. When I attempt to open SSMS, it says something like components missing, reinstall. So when I repair it installs the same VS 2010 with same issue. We have an application with a SQL Server backend database. We have a vendor catalog and then import items to our item database. However, it fails and gives this error code below. So my question is: Could this VS 2010 error be causing this error or is this likely an unrelated issue? > mscorlib 06/18/2016 8:20:42 PM LoadSettings Object reference not > set to an instance of an object. > at PosBeData.Settings.LoadSettings() PosBeData 06/18/2016 8:20:43 PM Time > > Update To: 06/19/2016 12:20 AM 06/18/2016 8:32:47 PM frmImportAdd > String or binary data would be truncated.
