Imported Texture Crash/Missing Selection Screen Pictures.

[Prime8]

Ok, so I've created a local wrestler using The Rock's current model. As I've not unlocked The Rock and as I have no use for Titus O'Neil, I've replaced him with the local wrestler by going into the uncompressed PAC file and replacing his PACH file with the modified one from The Rock. I've updated the arc files but when I load up the game, it crashes whenever I select Titus (who's model should have been swapped for the modified one). After trying again, I reloaded the game but now all of the selection pictures are missing. It allowed me to select the modified wrestler but it just went to a loading screen and nothing happened, it just kept loading. I then reloaded the game but created a new save file on the Xbox hard drive (the other was on the USB drive with the game) and the pictures were back but it once again crashed when ever the modded wrestler was selected. What am I doing wrong? Please help.

Sorted it out. I forgot to change EPK8 back to EPAC. It now works perfectly. Still having issues with the save file that is on the same hard drive as the game but that could be the problem in and of itself (I saved it there because I thought it would be easier than transferring the save file across once we have a save file editor up and running).
