I have seen other similar UN-Answered posts and hope MSFT chimes in to help.  

The issue symptoms are as follows:
1) Successfully publish a form to WSS Forms Service, and activate.
2) Subsequent publish process and approval appear to succeed (no error) but
the form will not load, and an error is logged to the WSS application log
stating
"An exception occurred during loading of business logic."

An exception occurred during loading of business logic. (User:
