Class Not Registered

When I click on the play online viewer, it opens up the playonline screen for about half a second then a little window pops up saying "class not registered". I looked all over online and everything people are saying is it happened to them well installing on a different machine, or reinstalling. I did nothing of the sort, last night when I played I logged off correctly, I haven't installed anything on my computer in weeks. It was working 100% fine, but when I went to log on this morning, it wouldn't work.

Something messed up in your registry maybe?

You can save the install folder of the game somewhere else, and re-install the game. Then copy the old folder to where you installed the game so you wont have to do all the updates and stuff.

thats the only thing i can think of.

I tried a system restore point from a few weeks ago and it works now. ^^ ty tho for the help!!
