Yes, after uploading my wallet, i ran the miner, but it didnt work, not on my server (which collapsed today) or on my pc.
Reinstall everything?! Is there no way to remove this virus without reinstalling everything?
I've heard from the pool in an email.
No, just 1 other was mining there, but for the first 100 Miners, there is an reward of 10 BTC. But i never got them

Wait, you got some random email from someone you dont know offering a 10BTC reward, you "uploaded your wallet" (??), downloaded a binary, ran it on both your server and your desktop ? Are you
serious? Can you post that email with header?
Ill be honest. Nothing you say makes any sense. You are supposedly a newbie that has no clue about bitcoin, you never mined before, only now with a miner that isnt a miner but a trojan. Yet you claim to have lost bitcoins? Moreover I can not find any single reference to this cross miner thing in google, other than in this very thread.
Ill give you the benefit of the doubt, but it seems quite likely you are the very same scammer that started this thread.
The cross-miner thing is what he mentioned: crossminer.tk. It resolves to the same IP address as wotan.cc
Other than that, it doesn't make much sense. I'm currently having a conversation with him through email, let's see what turns out of this...
