I noticed that you updated your system to 6.0.2. A couple things to check on that may remedy the problem.
1)Did you install the application builder after upgrading your system to 6.0.2? You will want to install the application builder 6.0 first, and then add the 6.0.2 update to the whole system.
2)Have you mass compiled all of your VIs since the upgrade? You will want to make sure that all of your VIs are in 6.0.2 format before trying to build them into an executable.
