I have a forms process that takes data from an initial submission and then through a workflow additional forms tasks are started.  For the most part the process is working great up until the subsequent users attempt to either approve or deny the forms processes they were assigned by workflow.  They receive the below error.

Laserfiche Forms has encountered a problem.  Invalid form data was sent to the server.  This can occur if the form is out of date. Please refresh this form and try again.  [LFF2106-InvalidDataSent]

The weird part is that the processes receive the error for 3 of the 4 branches I have in the workflow.  There is 1 branch that works perfectly.

I have verified that the recycle and timeout settings in IIS are not the issue.  Does any one have any ideas of what I should be changing to get this to work?
