Heya, please PM me your patchwise.log (open it with notepad), file located in your ArmA folder.
There are 2 language patcher files included in the v0.9, which should be labelled with v1.02 and GERMAN or CZECH... please verify you take the correct file.
If there is no log file etc, and the file seems to be corrupted everytime.. try deleting all files related to it, and retry downloading it from one of the mirrors. Too much overclocked CPU/MEM, overheated CPU/MEM and or defective CPU/MEM, can cause corruption while unpacking btw... but afaik Winrar should give you a CRC error then, and not the patch itself
PS Sorry for late response..
HI:
Patchwise.log is empty...
Sure I applied the correct file; german to english...
game work fine, and the system is quite stable...
I will reinstall game and patch again and see what happens...
Saludos
