I installed the WoT mod, but when I try to claim a reward/code, it says "Another reward has already been claimed," and the inventory shows a 404 error. These are new accounts, and I haven't claimed any codes previously. I tried creating new accounts and using the Opera browser, but since it’s tied to the IP address, that didn't help. I am unable to claim any rewards at all. Please look into this and provide the code manually—thanks.
