1.) Post a syscheck
2.) I don't understand what you mean by "and it also freed-up my HDD".
3.) If you're playing off of a HDD, the region-free option in Priiloader doesn't matter. That option is only for physical discs.
I'm not familiar with CFGLoader, I'm sorry I can't be of more help.
Ever since the new guide came out people have been reporting a lot of issues with CFGLoader and when they try and switch to ULGX they experience issues because of the weird d2x cIOS bases. IMHO, they should not have changed the cIOS bases.
