@JessT I presume you've already read through all 18 pages of this thread?  Please stop copying and pasting the same "help" directions to people that are telling you their software will NOT open.  I don't know what is more frustrating .... the issues with the software or this forum and lack of support from Quickbook's team members.  Now I am getting email notifications with this type of help and NO REAL ANSWERS.  Can someone from Quickbooks tell us when this will become a serious problem to them and when a fix will be available?
