|I had problem with MJ installation from day one 9/4/10 and have been chatting with MJ tech help numerous times (the best - top 10% they said) and by now I could become one of them (top 10%) because I knew ALL the drills they suggested.. Paste 'setup' in 'Start up' folder, delete 'mguspsp' folder, upgrade, run 'Fix it', run "Java', ininstall MJ, format MJ usb drive... blah blah... NOTHING works! By trial and error, even though I am not the PC savvy person, I nailed down the problem to ONE sure thing. There is positively a serious conflict between MJ and Norton anti-virus during boot-up. So this is what I did and it works every time.|
1. Disable Norton anti-virus for 15 minutes or less if you have that choice
2. Plug in MJ jack and it should start normally
3. Enable Norton anti-virus after that (I do have window defender on while I disable Norton though)
My problem with MJ is that it hangs/freezes for a long time before it could start and it could take more than 30 minutes. During this time, my PC was slowed down markedly and everything I tried to turn on become 'not responding', even the Task Manager as I tried to force-close the apps so I had to turn off the PC numerous timse to reboot.
It was not fun going through the drill all these past 7 days but at least I found a way to work around MJ and it works since then. The MJ techs are nice and polite but I don't think they comprehend all possible scenarios and it is frustrating as hell as they have you run through the same drill every time and it didn't work. I think they all use the same cookbook on that and as you become frustrated, you just disappear and their problem goes away. Simple as that!
Another annoying thing is that I can not turn off MJ from the PC interface, you either sign out, then unplug the MJ or use Task Manager to close MJ. There is no option to 'Quit' MJ or to 'Safely Remove the external hardware'. The MJ icon on the tray doesn't show as an USB drive.
I don't think MJ is really ready for mainstream as it is not straightforward as they advertised. It is 'hit or miss' as I experienced it. If you know how to work your PC decently then you can get it to work when you run into problems, otherwise you may ask for a lot of troubles when MJ starts coughing.
As always, before you do anything drastic to your PC, create a restore point, a backup, and record all the actions you do so that you can trace back if things get too complicated.
