Several of us that was having this issue all had an update this morning for QB's.  We all ran the update and everyones QB's is working great!!  I think the issue was when first opening QB's.  I tested it a few times Friday and just logged off of QB's but did not close QB's all the way and was able to get back in right away, but if I closed QB's all the way and tried to log back in that was when it would crash.  But anyhow the update seemed to have fix the problem so far!  Thank you for all your help!
