A question that will no doubt be asked: What device are you using?
Is the time zone set correctly for the device?
Was it running ok before and this just happened or is this a first attempt at using IVue?
You could initially try going into iVue's set-up. System > My add-ons > All > Choose iVue > Choose Configure > At the top, scroll to Guide Fixes at the far right > Click "Yes, Delete Guide Data Files..." (2nd from bottom)
A dialog will keep popping up. You will have to press Ok about 10 times. This is "normal."
Go back to the same page and choose "Yes, Delete Addon ini file" (the bottom item). Restart iVue. It will rebuild the addon.ini file and will import a new guide database. Report the results.
