Cannot get TV listings, no matter what.

[reboot]

I'm using the latest gb-pvr and have been using mc2xml successfully for a year. Now I get nothing. No Show Details.
The xml file is there, at 17,098kb and i've set config to read it from it's location.
I've tried updaing the epg from:
a) right clicking the icon in the taskbar.
b) the Settings button in the interface.
c) the config screen, xmltv source, settings update epg.
I've emptied and redownloaded multiple times.
I uninstalled, removed and deleted all of gbpvr and reinstalled.
I've looked over every post I can find, with xml epg issues, and nothing i've tried will work.
I've downloaded and am using the latest version of mc2xml.
I've double checked that my zip code and location are correct.
I just cannot get gbpvr to "read" the xml file and put any data in the tv listings.
Any clues?
Attached are all the logs i could find.

[reboot]

Nobody has any idea?

It looks like you've got your capture source xmltv settings configured to look at an xmltv file that doesnt exist.

Well...it DID exist, and it's there, I just checked, so after updating the guide all 3 ways again, it's come back...when I haven't had it for 3 weeks...very strange.
