It is indeed... Frodo pops up for me... and I've rebooted, re-installed and retried... I can only think you have some changes made that may have affected it.However, when I select C64simple and click continue the dialog box disappears and nothing happens, just llike before. I presume Frodo is supposed to run.
Have you tried booting without a save file (pfix=ram) and then installing the bugfix?
This should help you test that...
