Sorry, I don't really know what's going on. I tried your gamertag on mine and it's working flawlessly.

What Adium version you are using? Can you try deleting that file above and com.adiumX.xboxlivestatus.scripts in the same folder and see if that works? Don't make xbl as your status yet, just set it to available and then switch to xbl after deleting the pref files.

If it still doesn't work, send me a quick email at markcas (at) gmail (dot) com and I'll give you a modified version of the script that doesn't do any caching.

It might have failed on the first try and it's showing you the cached text. Most of the time this will be corrected on the next refresh so just keep your status up for 5 minutes.

If you don't want to wait, you can force the refresh by deleting com.adiumX.xboxlivetimer.scripts in ~/Library/Preferences/
