Runtime error on trying to launch the software

[claireg]

I had locked my PC with Actinic open, and when I returned and logged back in The Actinic area was black and unresponsive, so I closed it.
Now when I try to launch it I get this:

Microsoft Visual C++ Runtime Library
Runtime Error!
Program: E:\Program Files\Actinic v8\Catalog.exe

The application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Any thoughts?

Nevermind, I reinstalled it
