Ok so a patch for WWE2k14 is out, you can download it here (Thanks jeffsdomain for the upload)
http://www.mediafire.com/download/pvv8rpharitz12r/WWE2K14%20Title%20Update.rar
Make sure you back everything up before you do this (Entire WWE 2k14 folder plus savedata etc just in case)
In order for mods to work after the patch you will need to patch the xex with the title update because if you just have the patch in the cache (like you would with most patches for games) then the patch files
