Agree with signals...I was about to post a similar response...once again, it pays to be old and slow...
thanks pard...
Absolutely uninstall everything related to Fab 4 & 5...frankly I would uninstall v.2.9xx as well. Keep the install download just in case you might want it...although it's horribly outdated, but uninstall the program regardless.
If you have trouble deciding what to uninstall, StormJumper has a great guide to help out with this, just look for one of his posts.
Definitely run a registry cleaner...Regseeker is a great little utility...free and very effective...link in my sig.
In addition, you might want to consider doing a system restore...to your last known working configuration.
Good luck.
