This is new problem - I do not recall changing anything.
Just trying to open interface for SWAM Alto Sax getting error dialog box:
C++ Runtime Library
Program: C:\Program Files\brainspawn\Forte 4\forte.exe
-pure virtual function call
Opening The SWAM Clarinet is giving me "A problem has caused your program to close"
Were you given the opportunity to upload the crash dump?
Has not recurred. So just probably something weird "that day"?
