I think this is the file that is probematic-if there is a way to replace this file with an older version, come sumone give me a link. Thanks

What OS?

that is a problematic file. My problem (but maybe not opengldude’s) is in XP. This file was supposed top be fixed in the first service pack, but wasn’t. And, not suprisingly, there is conflicting info on the MS support site. The Knowledge Base Article states that the (english) file version should be 5.1.2600.21, but the version in my service pack files is 5.1.2600.1106
this sucks! I can’t make my WorldBuilder 3.0 work right!
