Invalid items in game

The items I started with including my main weapon and ranged weapon are showing as a Red ?. Items I purchased from a vendor do not have this issue. When I attempted to use my starting ranged and melee weapon a message of "You must have a melee weapon equipped" Or ranged for the ranged. The new items have no issue. However, I went to purchase some rough arrows from a vendor but I'm unable to equip them. They are showing up with the red ? as well and I'm met with an error that says "This item can not be equipped" when attempting to add it as my ammo.

Any ideas as to how to resolve this? My game files seem to be correct. I did download a new set of files from a different source but I'm met with the same issue.

Delete WDB, inside Cache folder
Check you are using the correct WoW version, Warmane support:
Wotlk 3.3.5
Cata 4.3.4
MoP 5.4.2

Did that, but no dice.

I'm on WotLK 3.3.5a 12340 Release
