i have win98SE already on my system, i had WinME about 4 months ago and removed it. i can install WinME back again, but i no longer get the option to back up my Win98 files. is there a reason for this?

the reason for moving up to WinME again is to see if it fixes a prob i have with ICQ2000b, as when installed, i constantly get an "error with mfc42.dll". i have replaced this file from my Win disk, removed it completely before reinstalling ICQ, and the prob remains.

any help is mucho appreciated.
