I finally managed to find Roland GS Advanced Editor, but I can't seem to get the program to work properly on my Windows 7 Home Premium computer.

Once installed, I have all of the files where I want them, but when I try to open it, it closes immediately with an error sound. Then when I try to open it again, it says, "GSAE was not finished normally last time. Finish GSAE once if having any wrong point. And restart after deleting 'GSAE.ini' (in GSAE folder)."
Then when I close it, another error sound goes off, but nothing else happens. If anybody could tell me where the error could be occurring and if I need to run it in a compatibility mode, please give me some help!

Thank you!
