If you're using Riivolution, you may not have your .xml set up properly.
If you're using Gecko, you may have forgotten the File Patch Code.
And I usually use sc_selchar with common5. It may work.
common5 is for riivo, sc_selchar is for gecko users. i've heard using both can cause freezing but unsure. i've always used the sc_selchar.pac with no issues.
