Ahh, ok. Thanks for posting up the error - that really helps.
I think all you need to do now is to re-install the bootloader, or if you're in the IDE, paste the line
load("bootupdate.js")into the left-hand side of the IDE and press enter.Since the firmware changed, the 'boot' file that was created was out of date. Usually it's not a problem because you update and features are added, but when you downgrade things get confused.
