Dear, Customer service team.
On Windows 7 operating system ,
Studio One 4, can install it properly.
But When closing the window and reopening the program, it can not be loaded.
Please give me an answer on how to solve this problem.
Will await your prompt reply.
(Please note that I even tried reinstalling the program and also upgraded the window system, but it still doesn't work properly. with my concern this error occurred after program upgrade.)
