Acronis Home ver. 11 Build 8101: Backup of My Data;Failed to detrmine correcsponding partiton path?

I've tried every option to do a backup of User data. I've tried the Catagories preset in Ver. 11 and creating Catagories to backup Documents & Settings, Shared Folders, etc. but I consistently get the following message and error codes.

"Warning: 11: 0 (0xB0000) {date/time} Failed to determine corresponding partition for path (c:\; {(, E:\;, H:\){any drive avaliable}} | Backup operation will not snapshot that path."

Acronis will backup "My Computer" to a different Backup location on a different partion on my Removable USB drive but the Location on the same drive but different partition "H:\" it has a problem with. Should I format and relabel as "F:\" vs. H ?
