Error opening Cataclysm Classic Professions (AddOns folder empty)

When I open the second profession (i.e. Open First Aid, close it, open Cooking) I get 13 errors in the Lua Error frame. Most are C stack overflow. I have attached 1/13 below, the rest are at: www mediafire com
/file/k642hec9tys74gq/Bugs.zip/file.

I ran Scan and Repair with no change and have deleted the World of Warcraft/classic/ folder and reinstalled but the error still occurs.
