Important xploder question. Please read...

[Cel_Ro]

Can someone please tell me if the xploder cd 9000 (the one you can download from the net to use as a psx boot cd as well as a game enhancer) as any kind of protection or is in anyway incompatible with the ps2. This is what happened: I downloaded it from the net, burned it using cdrwin and it booted just fine on my ps2. But every time I try to input a new code the screen just freezes, I can´t do anything and I have to reset the ps2.
Sometimes it even freezes when I am just looking at the codes that already exist on the cd, but when I going through the other options on the cd nothing of this happens, it only happens on the codes menu!!!!! Can someone tell me if this has ever happen to someone else or how I can get it to work properly? Like I said before I use it on a ps2 (pal).
