Error in Outlook 2003 - Save Task Order

Outlook642
I have been getting this error message for several weeks whenever I add a new

task. The save task order command is not available, but if I clicked close I

could add the task. Now, the system is no longer allowing me to save any

tasks. I get this message with the addition of one or more parameters are

incorrect and I cannot resolve it. I have tried:



copying all tasks to a new folder

running /cleanviews from the cmd prompt

running the outlook repair utility

working offline from my exchange server

uninstalling an add-in I was using



What can I do????
