Sounds like more of a problem with Lytec. Almost like it's reporting the wrong error. That looks like the right command line. Do you have the Maintence Utility? You can try that one. Other than that, it might be time to call Lytec. You can also try a third party tool or dev tool. For example, you can use the Btrieve Rebuild DLL (
