I did all these things, downgrading multiple times to 6, upgrading to the 7 desktop only, and now it's functioning like nagware. For every passcard it has to fill there is an upgrade message.
I'm glad you got yours working but the truth is they want more money. And they want it right now. You can check their FB wall where I questioned them about this. They don't deny it.
I posted this in the other robo thread in Dec:
FYI - the latest update •Official Current version of RoboForm is 7.1.0 has a separate d/ld for FF RoboForm for Firefox v1.1.1
Pure Firefox extension that does not require the regular RoboForm installer.
Requires RoboForm Online.
Which is NOT free

JUST updating IE disabled the old Firefox extension!!!

Then my laptop died, and when I emailed them for my acct info, they sent the link for the 6 version, and because of this, I know not to check for updates.
Seems to me they will do like microsoft - stop providing service for older versions. If they do, I won't be happy either - I took the plunge after using the free version for about 1 1/2 years, BECAUSE it was supposed to be $30 for life.
