Recovery Points not available

Hi there, I'm attempting to perform a one time virtual conversion and when I attempt to select a backup source, it says the recovery point isn't availalbe.

I regularly run full backup sets to a NAS device without issues. When I use the recovery point browser it says there are none available but I can use the browse option to locate them and open them no problem... but I can't use the one time virtual conversion.

I've tried restarting services, rebooting, etc. but without any luck.

Any suggestions?

Thanks in advance!
