Default [Q][RECOVERY] THL W8 8GB ClockworkMod

Hi, I decided to put GravityMod 2 on my thl w8 8gb. So I tried ClockworkMod first, for backup reasons following this guide. I get stuck at step 8, where i click download and connect the phone. Nothing happens the Flash tool says searching and the phone just starts charging. So what am I doing wrong?
(I didn't post a reply in the thread, cuz I can't I'm a newbie).
Any help is appreciated hanks

I use win 8. And that could be the problem, because maybe the drivers don't get installed properly or something.
I installed Win xp on a virtual machine and tried from there but no dice. I'll try with a standalone xp and post here if it fixed the problem.
