I’m glad you got it working!
It’s possible that the registry key somehow got into a bad state.
If it happens again, you can download and run (double-click) this file:
http://skjm.com/icampro/CleaniCamProKey.regThat will erase the current iCamSource settings in your registry. You will need to re-enter all of your settings, but hopefully the problem will be resolved if it’s due to a problem in the registry.
If you have any other issues or questions, please let us know.
