I see. Did you import the resources all at once? If you do it one at a time and test regularly, we should be able to narrow down the culprit. So you can safely add all the graphics and audio at once, since they aren't a problem, but after that try importing all the maps but no scripts, and see if the error appears then. If not, maps are safe, and import major scripts one at a time. So first the menu, then test, then all the miscellaneous scripts, then test. At some point, one of those should throw the error. And just to be 100% safe, test the kit you're transferring to again before importing anything to make sure it actually works.
