RE: PM System?
I am assuming you are using Firefox as this is a common problem with that browser for some reason. Firstly, try using an alternate browser just to make sure (ie Chrome, IE, Safari, etc). If things work at least you'll KNOW it's that and not something else. After that, empty your Firefox browser history and cache and then turn off your add-ons. After that, do a hard restart. Hopefully this will solve the issues.
