WebEPG Grabs no Data (1 Viewer)

[dakioms]

I'm using WebEPG in the US and I've followed the guide in the manual. Everything seems to be set up fine. BUT nothing gets grabbed by WebEPG. I end up with a TVguide.xml that only contains the channels but no programs to go with it. I checked the logs for WebEPG.log and it came up with this:

I noticed that it seemed to be a timezone problem and that my tv_yahoo_com.xml file lacked a timezone tag. I put in "Eastern Standard Time" and it got rid of that error but still failed to get any channel information, doing the exact same thing as before:

I do not know what to do next. Is the grabber file itself messed up? Is there a fix for this? Or should I just try using another grabber (like xmltv)?

Thanks.
