3.52 M33 Help - freezing up with custom XMB

I'm running 3.52 M33-3, and having a little bit of trouble with it. The XMB will load just fine with a custom XMB, but I can't load PS1 games or even access system info with a new theme flashed.

I've heard something about converting themes. Can someone please explain this to me?

there are themes that make 3.52 not work, make sure you are using a theme ONLY for 3.52 or else you will experience those bugs..if you don't have a backup of your flash0 I suggest you reflash 3.52 m33 and don't put themes UNLESS they are certified for that version

Yeah,people say that 3.03 OE-C is the best because it has more compatibility on XMB themes,and homebrew stuff.

yeah, but seeing that some games need 3.30 or 3.50... its always better to use the newest version of the CFW (and for security reasons too!)
