Failed to import .mxf file

[sbdman]

Had to do a system restore point last week for a newly installed disk backup program (used just for a backup) that messed up rebooting. Everything was working great after the restore, all TV programs were being recorded, TV guide looked great, system rebooted smoothly.

This morning there was a WMC message correcting guide data, and I can't seem to get epg123 update to work right, so tried a Rebuild Database on the client.
Here's the log after the attempt, any help would be greatly appreciated;

Looks like there are 2 things going on here. The first error is the first point at which epg123 is reading the cache file. Something in it was not right and threw the exception. At that point, there was no new mxf file created (or shouldn't have been). The second error is loadmxf trying to import the mxf file and it is invalid, followed by epg123 opening the mxf file to read a status field within and getting the same error.

Take a look at both the cache file (c:\programdata\garyan2\epg123\cache\epg123cache.json) and the mxf file (c:\programdata\garyan2\epg123\output\epg123.mxf). See if the size and datetime stamps make sense. You can make copies of them if we want to do some forensics on them to see what they look like.

Open the configuration GUI, click the [Clear Cache] button, and then [Save & Execute]. This should allow you to create a new mxf file that will be valid and loadmxf will accept.

Thanks for the speedy forensics!
I already uninstalled the epg123 to try a clean install with a Clean Start, and the client gui wouldn't even popup. (long list of errors in the new trace.log).

Last month I made a full Windows Backup, just installed - must have removed any bugs from that disk image program that the Windows Restore Point may have missed. Now, program guide just updated.
Now working perfectly, again thanks for the last hope of keeping my WMC functioning with cable card!
