Was running so fine with ClipboardFusion for a long time till suddenly couldn't get any macro running yesterday. Anyone could advice what's the matter? I would really appreciate it!

The errors are something like these :
Predefined type System.Object• is not defined or imported
Predefined type 'SystemString' is not defined or imported
Predefined type 'SystemString' is not defined or imported
Predefined type 'System.Object• is not defined or imported
etc.

I have attached the screenshot and macro I'm using.

I recognize this problem. At home I have several computers running CbF and suddenly I had the same=your problem in one of them. All other computers running CbF fine. The cause of this problem? Could be anything. At the end I decided to remove CbF and install it again: problem solved/disappeared !!! Reinstall is some work to restore all your settings. You could export your settings before removing CbF and then import them in the new installation. But I prefer to have it all clean. You do not know if your are importing your problem

Much appreciated for sharing your case, C# Clouseau!
I agree, sadly it could be anything. Have followed your way, uninstalled CBF, restarted computer, all clean. Reinstall without importing any setting. Unfortunately problem still exists. Have tried to update .Net and Windows, still no clue. The last thing I want to do is to reinstall my Windows but it's a pain to setting all over again for the whole computer.

If anyone has any idea, please know that I would be glad to know. Thank you again!

Bad news. A Win-reinstall would be my last one. Desperate! And no guarantee at all it will solve your problem. Uninstalling one or more of the last Win-updates?

Or back in time with an available restore point?
