That the only one ya used?
If CUPASH didn't give an error it "should" work...
It's really kinda hard to say what's wrong.

So somewhat of a checklist.
Does it only freeze when csp is included?
Any other codes on?
What region are you (NTSC/PAL) and are you using a matching one for CUPASH?
But really... we can't help with just that info. The texture pack is up there and ifyou are the only one with this issue, then it's something on your end meaning we need more info from you specifically.
