Operation Flashpoint 1.20 patch problem,please help

[AMDBildah]

I did all these steps,but here is where it stops...

<i>Create the following directory:
TempDir: C:\TEMP\UPDATE
Check that at least 160 MB diskspace is available!
Extract the official Operation Flashpoint v1.20 Patch to the TempDir.
Extract the unSafeDisc v2.40.10 archive to the TempDir.
Execute Safedisc_v2_40_10_Dumper.EXE, select OFPPatch_Upgrade_1_20.exe [54,661,026 bytes] and click Open.
This will create the dumped ofppatch_upgrade_1_20.exe.data.bin file.
Execute Safedisc_v2_40_10_Rebuilder.EXE, select ofppatch_upgrade_1_20.exe.data.bin [53,800,608 bytes] and click Open.
This will create the build OFPPatch_Upgrade_1_20.exe file. </i>
Rename the rebuild sdv2.testme.exe to: OFP_120_Fixed_Update.exe
<b>Extract the Patch Archive to the game directory. </b>

When I run the OFP_120_Fixed_Update.exe, this is the error message that appears after the files are checked...

<b>Verifying Operation Flashpoint, version 1.10...
Error found in file OperationFlashpoint.exe (471659ad!=22243b18)
