No topic files when publishing from Frame 11 to RH 10

Six months ago, this worked with no problem.

And first of all, before anyone asks, the files I'm working with are all on my C drive.

I've updated the source content for a manual (just small things, like misspelled words--no structural changes), and when I publish from Frame to RH, it doesn't seem to pull in the topic files. It also doesn't generate an !SSL! folder at all. My topic markers are all still in place from the last time I published, and none of our settings have changed. We haven't had any software upgrades.

I am no RoboHelp expert, so please help if you can.

Thanks in advance!
