MegaEPG can not be configured on Vista Media Center

For some reason I can't get MegaEPG to work on VMC (Vista x64 w/TV pack 2008, Israel HOT, MegaEPG ver. 1.3.1).
This used to work very well in the past but recently I redone Windows from scratch and since then I can't get VMC to recognize MegaEPG. Only Hot EPG (which sucks) works.

I installed the certificate, installed MegaEPG, configured it, Ran it, updated all channels. Nothing!!!
Done everything according to the installation/troubleshooting guides. Registry keys o.k, service is running. Everything seems to be OK but noything is working for me. I can only get HOT EPG and not MegaEPG.

Any ideas/suggestions are welcome.

HELP!!!!!

MegaEPG does not support TV

MegaEPG does not support TV Pack 2008 (aka Fiji). Don't work with it, it worth nothing for Israeli users. I'd recommend you to go back to Vista for now.

All the new features (that were only half-way developed and tested in the TVPack) will be fully introduced in Windows 7. I hope the MegaEPG will support Windows 7 soon.

Thank you very much for your prompt and clear response. I will go back to Vista.
The funny thing is that before I reinstalled Vista, I did have TV pack installed and MegaEPG worked just fine. However, the sequence was that I installed MegaEPG way before installing TVP. I guess if you do that then MegaEPG does work.
Anyway, I will go back to Vista and hope this works fine.
