there are quite a few options, but if your not that tech savvy or dont want to be bothered with it, just call a mobile computer repair guy. I can recommend the guys I use (xpert solutions). they'll have it fixed/hacked professionally within a few minutes. They saved me from the same problem a while ago. you can book them online and they'll come do the work right in your office immediately. its worth the $80 bucks to have stuff done professionally.
this is their website:

i think the tech that always comes to our office is terry but any tech there is probably great.
