"No writer found on this system" error

when i use DVD2One and CopytoDVD, every other DVD I burn, I get the “No writer found” error. I then close CopytoDVD and then open Nero and Nero finds the burner & burns fine.

This error happens exactly every other time. 1st time, i do it, it works great. I dont close DVD2One. I then rip another DVD and run DVD2One and I get the error in CopytoDVD.

any suggestions? I am using the latest versions for both.
