Reply to Traktor S4 sync problems with new Traktor 2.5

Hey guys,

Sorry if this as been posted somewhere else - I did look but couldn't find it.

I recently installed new Traktor 2.5 to use with my S4 (my previous version was 2.0.2) but i'm suddenly having issues with the sync feature. In an attempt to resolve the issue i've screwed up my install and I have an important gig on Saturday so really just want to roll back to my previous install (which i've been using without hitch for ages) - but can't find out how to do it?

I know this probably seems dumb, but i've never had to do it before so would be grateful if someone could help, or point me to a tutorial or something?

Cheers in advance guys!
