OPFlashpoint -> How to reach 1.46

[Raul el Pelotud]

Hey.. I have everything I think I need to make my backed up copy of Operation Flashpoint upgrade to 1.46 but I'm having some problems, maybe someone can help me

Starting from the original 1.0 version I've done these steps:

After downloading Operation Flashpoint v1.20 [US] Serial Fixed, I applied the 'unnofficial' 1.2 patch
Then, after downloading OPF v1.20 & v1.30 Beta [US/EU] No-CD, I applied the 1.3 patch to the OPFlashpoint upgrade 1.3, then when I try to execute it, the 1.3 upgrade will throw lots of "Error found in file ????\?????.??? (checksumnumber!=checksumnumber), an example:

Error found in file MPMissions\1-8_d_FlagFight.ABEL.pbo (b8985413!=1f1ee374)

I can guess this means my OPFlashpoint copy doesn't match the one it should and since I had 1.0 I don't know if by installing the unnofficial 1.2 I may have lost the 1.1 upgrades...

Can anyone help me?
