Data File too short... Launch Error

[BearJude 0]

Getting the Error : Data file too short 'addons\samplemap_terrain.pbo' Expected  20855447 B, got 353187 B   when i try to launch.

I have tried reinstalling , launching steam as admin and checking for file errors.

Any ideas for a fix, couldnt find anything online except for Arma 2 AO threads

Ok i managed to fix it.

I started deleting all the files mentioned in the Error code, for example: Samplemap_terrain.pbo, Samplemap_data.pbo, samplemap3_data.pbo, samplemap_test2.pbo plus bisign files

and restarted the game until the error stopped and it launched.  GG   :D
