The problem is really with Pastebin.com and not TH so reinstalling will likely not help. TH is doing a call to Pastebin and it's expecting a version number to be returned. For unknown reasons Pastebin.com is returning "stolen content from Pastebin.com. your request has been blocked!" and redirect messages instead of the version number.
I too had issues this morning where it wasn't working and after some investigation I discovered it was returning "stolen content from Pastebin.com. your request has been blocked!". Eventually it began returning the version number and started working again.
