OptionsImport fails

I would like to test/work in the new RH 9 WIP, therefore I want to import all my options from RH8. I ran OptionsExport in R8 and then OptionsImport in R9 and then get the following error message:

Command: OptionsImport
Specified file is not a valid options file.

Confirmed. Just got the same error message.

Thanks for reporting
