3ds Max IES Light issue

I am using Max 2009 with photometric lights and IES profiles. The profiles load with point shadows as default, and I switched them to shape/area. Everything has been working great until recently, now the lights revert to point shadows after every render! Has anyone else be able to solve this problem? I tried merging into a new scene with no luck. All that was changed before it stopped working was I edited a material, blend of A&D and standard with a png diffuse and png mask. Could the png be causing a problem?

If Max loses the link with the ies file for any reason and needs to reload the ies file some of the parameters revert back to the defaults. This might be your issue.
