Code: C:\Users\KonradK\Documents\My Games\Beyond the Sword\MODS\Caveman2CosmosSVN Checksum mismatch while updating 'C:\Users\KonradK\Documents\My Games\Beyond the Sword\MODS\Caveman2CosmosSVN\trunk\Assets\CvGameCoreDLL.pdb': expected: afdcfd43bde27f2ad649471d86428c62 actual: a87422a46a1af60ce9d40034f16db90f Try a 'Cleanup'. If that doesn't work you need to do a fresh checkout. Whenever I try to update to any SVN Revision of C2C i see this error. The game is defunct; I have many error windows with texts relating to errors in XML files. I give try the non-SVN old Caveman2Cosmos v33.7 and mod in this version loads without problems.
