I have been using SDT with a VFP6 app for a couple of months and have just recently encountered a problem. The app is in use on our LAN and I am doing further development on my local C: drive. Periodically, I copy the database container files and the SDT meta files to the network and run the exe that updates the table structures on the network. When I attempted to do that today, I got the message 'unknown member oSDTMgr'. The app has not been moved, no paths have been changed, and the exe that does the update has not been changed. Does anyone have any insight as to why I am getting that message?

Thanks in advance
Stan
