Dear Professional Specialist,

 

would you help me how to solve this problem , when i try to creat a DVD menu .on the way it will suddenly close by itself

You need to be much more specific about what is happening.

Not knowing what version you have, normally in such situations, a re-install of Liquid over itself can cure unexpected behaviour.

My avid is ver 7.2

i don't know why it will close,but it close in a few min ,may be 4min may be 7min every time not in the same

My guess is that you are using a weak uncertified system with your render folders placed on your bootdrive, as Lew said, we need to know a lot more about your system, please add your system specs to your profile, you can click on my profile and take a look what might be needed to add.
