Few!! It's solved. It seemed that I had to something with the MTU settings. Never heard of that.. But it worked.
If someone ever gets this problem. Do the following:
Go to
http://www.dslreports.com/drtcp
Download the Newest DrTCP .exe file.
Run it on your computer.
Put "Path MTU Discovery" on "NO".
Click on Save.
Click on Exit.
Reset the computer and the problem is away!
Everything is fine again now. Thnx anyway!
