hehe...i just now fixed this problem on mine, ok, this is how you do it. go to your d2jsp program folder, then find d2jsploader.ini and edit it. find the thing that says game stop or something kind of like that. there should be a number by it that says 60 or 200 or something, change it to 5000 or so. that will make it run a LOT longer. i ran mine for all last night and its still running
ill give you more detailed instructions when i get home, k tweak?
