after coming back on soul seek everything i had is gone!

i was having trouble logging into soul seek so i had to end up reinstalling windows..this process kept me away for a little over 3 weeks..after the reinstallation i had no problem getting into soul seek with the same user name i originally had..but all the files i had ready to download were gone..even my users list had disappeared..there was nothing there..it was as though i had just logged into soul seek for the very first time..can someone tell me is there any way to get back what i had from 3 weeks ago or do i have to start all over from scratch?
