Don't know anything about Dell Remote Access other than it states it's no longer offered. If you have uploaded to this service, then contact their support. If you check http://www.dellremoteaccess.com/
there is a new alternative. Again, I don't know but possibly this service has taken over DRA and just needs you to install this new software to gain access.
As for lost files and factory reset. There is the possibility to get some information back but the more you use the PC and save data to it the less likely that is.http://www.active-undelete.com/http://www.livecd.com/
Youtube will possibly help you use these tools, LiveCD being a good first choice to try and remember download to a friends PC and use the bootable versions as any new data written to your pc may overwrite the stuff you need.
There's also Hiren's BootCD if you'd like to look for that.
A factory reset requires partitions (usually) so if you do have partitions you may have C & D drives as well as a hidden restore partition. The Factory Reset will only restore to C leaving D if exists alone.
Anyway, always good to backup to external and incase of text or photos of importance - print
Nah! That Parrot's just sleeping....
