We are getting the exact same problem - except that the person who built the InfoPath forms and did the initial integration is the only one who can open, edit the forms / processes, and deploy the processes.
All forms and processes are stored on a mapped mnnetwork drive, and the mappings are the same for all of us (m:\).
We have tried re-running the K2 Visual Studio configuration manager as was suggested by Mike Talley, and have re-run the InfoPath Integration wizard as well - neither of these have resolved the issue.
My biggest problem with this is that the InfoPath developer is rolling off onto other projects, and we need to distribute out the ability to update and deploy these processes and forms to other resources.
Any assistance would be greatly appreciated!
