The release date check could be bypassed anyway by using this method:
1) Run bf3.exe – it says the release date – October 27, DO NOT CLOSE!
2) Open the folder (C: \ Users \ user \ AppData \ Local \ Temp \ mtka_tmp)
3) If you have not closed BF3.exe, then see this fayl.otkryvaem lang_dfa.ini and change the line to
# GENERAL SETTINGS
ONLINE_MODE = false
MANUAL_MODE = true
… … ….
# RELEASE CONTROL SETTINGS
RC_MODE = false
keep lang_dfa.ini and put a check in the properties – read only
4) open bf3.exe and enter the CD-key (for example 3FQQ-NDVL-QPTB-FPFW-QYYT)
(this is not my method I take no credit for it)
