No, I'm not running linux, I'm running a version of xbmc I just built yesterday afternoon using the latest svn, and the AMT script also from the scripts svn. I'd had this problem before, but I thought I'd get the latest builds before troubleshooting.
AMT just won't start a second time, and there is no script output. Restarting isn't a big deal since I don't usually run the script more than once a day anyway.
Xsportscores won't start at all, debug output showing a list of modules that it tries to import, and then fails saying "importerror - no module named image".
All of my other scripts that I like to use run fine, afaik.
BTW- AMT is a superb script that has come a long way, I've been watching it for years... my compliments to the author/s.
