[PC] My2K login problem

ok, i read the intructions on OS via my2k login problems but it seems it's not working for me.

whatever username and password i enter, i cannot manage to login. i recall they requested some numbers to be put afer username or password and maybe i forgot what number i put.

so how can i reset my username or password in order to be able to login or how can i retrive my original uername and password?
