My original installation was BIAB 2012 everything. Windows 7 64 bit. The installation is on my second drive F:/bb and has not changed or moved. I installed the 2014 version right over the original in F:/bb. Everything was working fine after that. I was able to create and edit multiple song files. All were originally "saved as" and later played back several times when I rehearsed.

The song that first showed up with the error did have frozen tracks but after getting the error I unfroze them and did several restarts,reset to factory defaults, and updated to latest build. After that I tried opening different songs and got the same error when right clicking on the instrument tracks. As I said earlier the error only occurs when trying to edit instrument tracks on already saved songs. I can still create and edit a new file that hasn't been saved.

Matt, just so I'm clear on your suggestion you want me to delete the whole "bb" folder on my F drive and reinstall it back on my F drive? "F:/bb" That's where my installation is.
