Please be more descriptive as to when you see this error message. What are you doing at this time?
After upgrading LabVIEW, have you downloaded all the SW updates to your RT target? After that, have you opened your VI on your development machine in the new version of LabVIEW and recompiled it, or rebuild the executable, and then downloaded the updated VI/EXE to your RT target?
If you don't update all the SW on the RT target and try to connect from a LV 7.x developement machine to a LV RT 6.1 and VI on the RT target I would expect to get such an error message.
