Query: USELESS - constantly crashes and locks up my PC!

1 Star? It shouldn't get any!!!I'm an accountant and we had to buy this worthless program because a clients data was in QB 2006. EVERY TIME I open the program a) it takes FOREVER to open, b) it crashes constantly - the program will lock up and then just disappear - SWEET!, c) when you want to log out and go home make sure you have about a half hour to spare. The program will, hang, hang, hang, hang then give you a "not responding" error that will take another half hour to clear.DON'T WASTE YOUR MONEY on this absolutely useless product.
