iTunes can't find my IPod Touch 2g, and the IPod can't connect to internet..?

This is what happened:

I've bought new PC, and I tried to connect my iPod Touch to iTunes for 64bit Windows 7. something went wrong, I don't know what, but I couldn't find my iPod at iTunes. I disconnected the iPod, and after that, I haven't been able to connect to WiFi (Wireless Internet) nor bluetooth. I became so annoyed, so I ended up resetting the whole iPod to it's factory settings. Now, I can't do ANYTHING with the iPod. It shows a picture of a USB cable with an arrow towards the iTunes emblem. I can't do anything with it.

What I want you to help me with is: How the **** do I make my iTunes find my iPod Touch so I can synkronize it, and is it more of you that have this problem? Please, respond as fast as possible, I'm kinda desperate 😀
