Technic Launcher Updater is checking all the time

Operating System: Windows 7 Professional 64bit

Description of Problem:

I was able to play Tekkit for all the time, but since i started my PC on Sunday the Technic Launcher Updater doesnt work. When i start it, it just says "Checking Launcher Version" and the bar is loading all the time. Nothings happen. It doesnt close after a time, it doesnt crash. Its just loading.

I already deinstalled all java versions and installed the new ones but it didnt work.

I don't know why (and contacting BitDefender doesn't help either) but for some reason as of Sunday/early Monday BitDefender conflicts with Tekkit. I turned mine off, ran the launcher and there was no problem whatsoever.
