Napster, i think you might need to clear your cache and also do a dns flush (cmd ipconfig /flushdns ). I think the problems look like your end rather than server side, especially if you can't edit your posts in the main forum!
I'd firstly clear your internet cache. Not sure what internet browser you use but you could use an app like cccleaner to do it. But to flush your dns etc. Open up the cmd (command prompt and type ipconfig /flushdns (may or may not need elevated permissions). Then i'd reboot your router/broadband connection and computer.
