...I downloaded the latest mc2xml.exe and set it up but I cannot get any guide information...
Delete the xml and dat files in the folder where mc2xml.exe resides.
Double-click mc2xml.exe
It should open a command window and a dialog box to enter your provider and login details.
After filling that in, and continuing, you should see the command window downloading the data.
After it's done, look in the folder for the newly created xml and dat files.
If that's all good, open MC and go to Options>Television>Load program guide> follow prompts to complete.
