If you are now putting them in the right folder and are no longer experiencing the corruption issue, I can help you further by telling you to ensure that the add-on is properly installed. It should be AllodsOnline/data/Mods/Addons/AddonName/AddonStuffs or AllodsOnline/data/Mods/Addons/AddonName.pak.
If you are still experiencing the launcher corruption error, then you didn't follow my instructions the first time.

We need more information to help further if the issue is not resolved..
