Okay, I downloaded 3.5 last week sometime, then put it on my usb drive on Tuesday. After remembering to disable IIS and also uninstall a previous apache server and Zend Studio, it FINALLY worked on Tuesday. Then, yesterday, tried starting it up again and it loads the bluish purple screen with the logo then does the redirect, however once it gets to the Apanel nothing but a blank white page. So I've been struggling yesterday and today trying to figure out whats going on to no avail. I'm running a Vista Ultimate machine (dunno if that would effect anything). I've gone through the numbers, disabling services, shutting down AV and firewalls, ending processes, stopping start up programs, ect. Nothing seems to be working. Please help. Again, I had it working on Tuesday with the Apanel coming up, but now nada. thanks, Doug
