COBRT045 Attempt to OPEN an NLS file using incompatible language definition (Fatal)

The NLS control information for a file in your program does not match the same NLS control information in the header of your index file. Alternatively, your index file has become corrupted.

Resolution:

Rebuild your index file, or rerun your program using the backup copy of that file. If you have added a great deal of information since you last took a backup, you might want to rebuild the file using a utility that is able to read the data, if it is not corrupt, and build a new index for it.
