We're getting a lot of error messages since I installed the Oct. 24th update. Is it possible to go back to the August 7th version?

We get “An exception has occurred in the application” when t7ina.rwn is opened.  We get it other time as well but with T7ina fairly consistently.  
 
Also, when t7ina.rwn is opened “The field UDF1 was not found.  You may include only active fields in an expression to be compiled at run time.”
 
This issue varies from machine to machine but we never had the problem before the last update.

Thank You.  Looks like that did it.

Is this when initially loading Evo or after you have been in for a while?

My apologies for the super thread necro here, but I am getting similar error messages.  I am encountering these error messages when attempting to save a labor record entry in the D.C. login using DC-C.  I'm not sure if they're related to this thread or not.  I haven't had to reboot a computer yet, but it's consistently failing with the same data entered.
