Cubase 8 fails to start after changing mouse / keyboard

I was thinking I would switch to a wired USB mouse / keyboard from a Logitech wireless.
Tried starting Cubase 8.0.10 (Windows 7. 12 Gig ram, Quad processor). Several times.
Each time got a dialog stating Cubase failed to start and Windows was checking for a solution to the problem.
Same message.
Several times.
On a whim, switched back to wireless mouse / keyboard.
Really? Why in the world would that cause Cubase to fail? Is it really THAT sensitive? :open_mouth:
Is there something I can do / should have done to prevent this in the future (if I want to switch mice for example)?
Thank you,

SO … I am the only person this has happened to?
