All right, so I recently renewed my Dev account and went through the tedious hassle of getting all the new certificates and provisioning profiles. Trying to compile onto my iPhone 4 caused 3 of errors to come up, and I have solved two of them so far. However this third issue is the real killer. I've found nothing through hours of Google Searches and I am about to lose my mind. When I build I get this: It happens for both the simulator, and the Iphone. Note: A few hours ago it ran in the simulator fine but I now have the above error, and I have not change any code since, just some of the build info.
