kk - - thought about that cause he specifically referred to IE and not just 'any' old browser. Lemme check some stuff - and I'll edit this post with whatever I find.
update - ok...so there's nothing in IE: except usual nonsense like virus-scan, divx, flash media, java runtime, etc etc. I tried disabling everything in fact. No change. All of these *plug-ins* have been on the machine for a long while - even when the trainers did work. So - guess wait some more to see what you guys find out from your provider.
Ok, all updated to IE 9....still getting same issue but now - when I open the trainer(s) I'm getting weird little files being created with odd-ball filenames. one looks like japanese characters and the other is just symbols... tried deleting them and running trainer again, deleting them while trainer is running.... no go. Any ideas?
