HTPC and PVR the home for MegaEPG

Hi to all,
I'm using the software for over a year, and it works great.
Until last week.
I suddenly noticed the little pop up balloon saying the guide has only one day.
I tried updating the guide from the settings menu, but an error 14 or 34, something like that popped.
When I investigated, I discovered that it might be related to the time settings (and the clock is set correctly),
or to ADMIN$ privileges in the windows directory as mentioned in the Documentation. All of that were correct.
I tried uninstalling and using the default guide supplemented with VMC, but the same error repeated.
After some more snooping around, I came across the registry entry discSvc under Local_Machine\Software\Microsoft\Windows\CurrentVersion\Media Center\Service\EPG.
It was set to http://localhost:19679/epg/GetTvServicesMetaInfo. I deleted it after restart, and the normal guide came back.
Now, the normal guide to HOT is rubbish. I want to re enable MegaEPG.
After many installations of different versions with no success, in each of them the URL
http://localhost:19679/log
returned 404, I think the MegaEPG local server- or whatever it is is not working.
The service was enabled and working, but the port 19679 wasn't open (checking with netstat).
The firewall and antivirus were both disabled during the whole procedure, and I also tried running the the installer as Administrator in case there is a privilege issue.

Further, the directory MegaEPG in file://---/admin$/ehome/MegaEPG/data/GetTVServicesMetaInfo.html does not exist.

Could anyone come up with ideas for the source of the problem?

Much regards, Yarin
