I habe the same problem but I cannot even open Biab 2010 anymore. I get the 2010 Start jpg and than the error message and the program closes down. Before that happend I played around with the Soloist Maker and Real tracks. In some point I got an error pop up, that this was not possible. So I closed down biab and saved the song.

From this point I cannot even open biab 2010 anymore. Always get the error message with the bbw.exe I replaced the exe again, but nothing happens. Good for me, that I made the backup copy on a WD passport. I was running the programm from the WD passport. Than I tried it from the original Biab hd and it worked. Right now I try again copying all the files from the original hd to the WD again and hope that I can start the program later again from my WD hd.

But I'm kinda scared, that this is gonna happen again and I don'T know, what to do than.

So long,
mos
