Can anyone help me with how to open a song file created in an earlier version of Sonar in 32bit to 64bit.  Right now when I try to open something up I get the dreaded spinning circle.
 
Thanks,
Richard

Try opening the project in safe mode by holding the SHIFT key while opening the project.

As such there is no such thing as a 64 bit project. They are all 32 bit. The may contain pointers to either 32 bit or 64 bit plugins or both. They may even have pointers to 64 bit audio.
 
Any project created by Sonar will open in any later version of Sonar. If it wont open Scoop has the answer.
