Are you still getting any GUID errors?Have you loaded ALL the object libraries, see my post above

no errors since installing the dummy library... might give a try to Oz libraryAlain from Montreal

Alain, yep Oz libs is the way to go. As you can see I now only get one error. As Jim said once you have installed Oz libs delete/disable the dummy libregards

Thanks Alexander I'm glad it helped. One thing we do need to remember though is that duplicate object libraries are as bad as missing GUIDs, and since the "unknown" is now "known", we no longer need or want the dummys on our systems. They are now a potential source of problems rather than a cure, especially when you consider the popularity of the OZx stuff. I've removed the files from the server for this reason. Alpha117 you can keep your alpha117_dummy_lib.bgl, but let's get rid of the rest of them that everyone's downloaded and replace them with the actual OZx libraries. The upside is you'll also get to see an object in your sceneries that the designer meant to be there rather than the wooden crate. I believe we'll be seeing an update for Vashon that will eliminate these errors soon. In the meantime you can get the OZx libraries here.Jim

Thank you, Jim. Downloading the OZx library now and will remove the dummys and retest. Thanks again for all your help!!
