Re: Problem with CCleaner
I have never known CC to change a file association 😆 If you right click on a file you should get a choice named "open with" pick the program you want to use and check the box "always use"
Seriously I don't know how CC would change a file association unless it was due to a registry alteration. Careful with that part of CC and always back up your registry when you clean it.
The video thing is a flash problem that is common with any older pc. I frequently had the problem with my old box. I would just pause the playback until the buffering was complete or so far ahead the playback couldn't catch the buffering. That definitely has nothing to do with CC
