Remote Update and Cyclone IV

I am getting an error when trying to add a remote update component to Cyclone IV device. I have simplified the design to just a NIOS and the remote update. It builds on cyclone II and blows up on Cyclone IV with the following error

Internal Error: Sub-system: CDB_SGATE, File: /quartus/db/cdb_sgate/cdb_sgate_wys_gen.cpp, Line: 537

Cannot set param type 581 to a string parameter for WYSIWYG type 144

End-trace

Quartus II Version 9.1 Build 350 03/24/2010 SJ Full Version

Service Pack Installed: 2

I have the configuration set to active serial -> remote with default settings

Any ideas?
