On 21 October 2013, I posted "Not a valid terms code" on the Forum.  I had just updated Classic to 7/26/13 SP1 and was getting this error message.  I reverted to the 04/04/13 update.  The "Not a valid terms code" error disappeared but I now have a "Key Setup Error".  This happens when I am trying to enter a line item in SO-A, and I have to use the Task Manager to exit the system.  I ran DDCHECK in UT-A but there were no errors.
 
This "Key Setup Error" error has been on the Forum before, but the only solution I saw was a mention of a 'patch 3' on 6/18/07 by Lynn.  Where can I get this patch?
 
Would appreciate any help in solving this problem.

Lynn,
 
Thanks very much for your response.  I had already resolved this issue, on my desktop computer, by a tedious and long-drawn out process of trial and error.  
 
I had saved most of your upgrades, and starting with a 2008 upgrade, I progressively installed about every second or third upgrade.  The final successful installation was the 04/04/13 upgrade and there are no error messages.  I don't have the courage to try to install 07/26/13 yet!
 
I have another installation on my laptop computer and tried the same sequence, but I have not been successful, and am getting about 3 different error messages.  I want to try a couple of things and if still unsuccessful will post to the Forum.
 
Thanks
John M
