fatal error -- PREP I -- filename is not profiled, and can not import modified version version
For function-level profiles, PREP uses modified EXEs and DLLs, with modified names with extensions _XE and _LL. If any modules listed in the import table of a profiled module refer to another profiled module, but the imported module is itself not being profiled, then the import table of that imported module cannot be changed, and this error occurs. The solution is to include the offending module in the profile.
