Hi,
same problem here (-3 and 501 error)
Last night i had 501 error, this morning -3 error and this afternoon 501 error again :( and again.
i even tried offline registration but it doesn't work, the elicense program freezes when i click on "Save License request to File".
I tried to run TOW2.exe as administrator, i tried to re-install the game nothing works
Best regards,
Hitman
