- Try loading another .twd file and nesting it, to see if the issue is with a particular .twd file or if it is with any .twd you load. Make sure you are loading the .twd file from the hard drive of cnc control and not through a network source.
- If all .twd files are causing the issue, then try the following: Shutdown THM software, go into WIN Explorer, C:\Rolling Nest, Delete: "result.mdb" file, run lates Control Nesting update, open THM and try to nest .twd file.
