I am testing an additional option, RW Cutting. I made a system and then modify the options several times. It gave mediapool errors. It is very normal. And later I decided to create a new system instead of modify old system. It is also give mediapool error after add the virtual drive string. It is abnormal.

After that I try many thing, but can’t solve this problem. I uninstall and restall the 5.14.02. still not work. So now I can’t create any new system ether virtual or real system.
I must demo the new system in wednesday. Who can help me.
