Did you wipe before you restored? And do not misunderstand this, you cannot downgrade firmwares once you go 4.3 and up, but you can downgrade the system, which is what you did with your backup

thanks very much for the clarification, i was under the impression that firmware and system were somewhat synonymous in this context, i.e. if you upgraded firmware you were in effect upgrading the system, but i see that's not the case, again thanks. and yes i did do a full wipe before trying to restore the backup, was i not supposed to?

Updating firmware does update the system. Based on your previous comment the only thing you did was update the system by flashing a ROM which only contains the system, data, and kernel, so you can still flash the 4.3 firmware. Firmware consists of bootloader, recovery, modem, and system, what you cannot downgrade is the bootloader, the flash will fail every time because it will try to downgrade it. And you should not experience any issues restoring your back up. What were this problems?

but the cm11 rom zip i flashed included 4.4.2, before flashing i was using 4.3 - so didn't i update (or change) both the system and firmware?

btw, fwiw, - now that i'm up and running thanks to skipjacks help, i decided to try restoring my 4.3 backup again. when i tried this in the past it would restore to the same state as it was before but it was virtually unusable because of severe lags and multiple app not working popups that made navigating almost impossible. well now when i try to restore it fails and i get the following message:

checking md summs...
md5 mismatch

md5 mismatch

update:

well it looks like the *.md5 file was pointing to my internal drive rather than external which is where i had moved the 4.3 backup (and apparently the *.md5 file didn't update or account for the move), anyway i copied the backup to my internal drive and, viola, no more md5 mismatch errors. more importantly, it restored the 4.3 backup perfectly, in the exact same state as before, without all of lagging and pop up issues i was having before, so i'm one happy camper! not sure what i did the first time around, but all is good now, for he time being, sure wish i knew what i mucked up to cause the problems in the first place, i really have no idea, other than being a newbie at this. also, fwiw, the tiny text in the upper left hand corner that appears during boot (kernal message) no longer appears now that i have restored the 4.3 system backup... fwiw2, i'm liking the philz_touch_recovery but it sure has taken some getting used to, the commands are so close together and the thing is so sensitive, very easy to accidentally select the wrong option, and some of the wrong options aren't too friendly if it wasn't what you had intended to select.
