lawl I saw your problem right away. Has nothing to do with CRCfix, but rather, iwi_x_dds.
When you convert stuff, especially in BO, when it has the "~" symbol, dds_x_iwi will turn that tilde into a "_" when it converts it. So you have to go back through and redo all of the "~"'s in the title. iunno if it does it with other characters as well, but you should watch out for that none the less.
