Xbench doesn't launch anymore

Hi, is there anything we can do, if XBench doesn’t start anymore? It starts up, signs in and then gets stuck…

Everything was fine until yesterday. There may have been an Windows Update in between, so I set the PC back to some days ago, but it didn’t help.

I also deinstalled and reinstalled XBench without any succes.

It runs on Windows 7 Professional 64 bit.
