From whom did you get that message? It seems strange because there is no 
supported direct path from 10.04 to 11.04 (except a fresh install, but 
that's not an upgrade).

Which Nvidia card do you have? Can you post your "/var/log/Xorg.0.log"? 
Maybe there is a hint why the driver doesn't start.

Perhaps you should blame Nvidia - if you use their driver it isn't open 
source but you rely on the support of Nvidia just the same way you did 
with Windows. And Nvidia still doesn't support Natty for older cards

If it is really urgent, you might consider paid support from Canonical. 
Other than that, you could do a fresh install of 10.04 to return to your 
previous system. You can keep your home directory if you select manual 
partitioning and select to not format the partition. Probably you know 
already that you should backup your valuable data first.
