ATL Error when builing release version

[Matt Gates]

My project compiles and builds and runs fine for debugging but when I try to build the release version I get the following error. Anyone ever seen this before? error C2065: '_AtlModule' : undeclared identifier I should mention that I was able to build the release before without a problem, then one day this showed up. I'm not sure what is going on. TIA for any assistance. Matt (Padawan Learner)
