Hi,
The project settings and the general CVI setting use the same script to talk to the Source Code Control software, if one works, the other should also work. Actually is the same dialog box that you access from diferent places. What type of errors do you find in the general CVI SCC settings? What SCC software are you using?
You ma want to create a new workspace and try this the SCC configuration again.
Let me know how this goes.
