Perception parsing errors are basically always from those AI files being there, so I suggest checking again. Delete the folder named scripts if it exists.
Then go into the XML folder, and delete the folder named AI and ENUM. Make sure you are deleting the whole folders.
If you have Steam, that's
C:\Program Files (x86)\Steam\steamapps\common\Star Wars Empire at War\corruption\Data
If GoG:
C:\Program Files (x86)\GOG Galaxy\Games\Star Wars - Empire At War Gold\EAWX\Data
If Disk:
