I've just purcharsed bronze package trough steam, got confirmation of it on mail, preloaded HL2 and on my "games" CS is still in "purcharse" status.
What i have to do to play CS?
Nah, it's all good now.
Problem was "clientregistry.blob" file where all stuff, operations and preloads are written down. Now, when i bought game on friends machine, transaction was saved into his steams "blob", not mine. So when he logged out, i deleted mine blob, restarted steam and everything started to update from scratch.
Not sure if i've explained it clearly, but problem is gone now and it's all that matters.
