Efile transmission not going through, error code 2

I am using TT Home and Business.  I have completed a federal and a state return.  When I transmitted the files, I received a message saying "We are experiencing internet transmission problems.  Your transmissions did not go through.  Intuits Electronic Filing center did not receive your returns.  Please try again later.  Error 2"

I tried several times and kept getting the message.  I loaded TT to another laptop and still received the message.  On the second laptop, I then only transmitted the federal return and it successfully transmitted.  I then tried transmitting the state file and again received the error.  The state is WV and the return has a attachment.  

I then loaded TT to a third laptop and attempted to efile the state and received the same error code. I have  made sure pop up blockers are off, cleared cache, lowered the windows security setting to medium and set to default.  I have downloaded all updates for TT.  The file size I am uploading is 11 MB and a pdf required by the state.  I do not know if the file attachment is the issue but is the only variance from the federal file which did transmit.  

Has anyone else experienced a similar issue and found a fix?  I dread calling customer service because they never seem to be able to help.
