Hey bro
jus check wat payment options are they askin and how secure is it. Coz u knw very well abt Credit Card frauds so only if ur fully aware then only proceed with tyhe payment options coz the sites require Master/ Visa/ American Express cards wich are valid for US use only so if u hv a card that is valid for buying items from the US then only proceed and Please i repeat do check the genuinity of the payment..as u hv already said that u knw wat mode u hv d/laoded so it will be advisable to contact STEAM (via email) and then ask for their confirmation stating the procedure that u hv gone thru in d/loading the game via net (tat particular site) Coz most of the sites fool ppl by taking their Credit card info.
So post ur confusion and i wil help u out else contact STEAM thru their website by emailing them and telling ur product that u hv d/laoded (CS-CZ) in this case..
Post ur results too....
Cheers n e-peace.....
