cool game, but, uh, how the heck do I progress? in the PC I tried writting the username as Stoyan, password 385320 but that didn't work. Also, in the basement, I unlocked the box with the code 642986 and it showed me "game over". help?

Nope, you got the DOB part wrong.
3YY + 2MM + 1DD is = 01 (Miglena's year) + 04 (Katlina's month) + 24 (Stefania'day) = 28
The order for DOB is in the subjects missing posters, see if you can see now :)
T9(T3-T2) = 38(39-34)=190 Which you did correctly!
28 x 190 = 5320
Huge apologies for the confusing puzzle, I'll be updating it in the updated game version and make it easier to avoid confusions.
