Hi, I get a totally blank error message when I open Studio 2021. It's just a box with the word "Error" in it next to a red cross. There's a picture of two disks in the bottom left corner. Initially I could open Studio OK and I only got the Error message when I tried to open a file that I've worked on already, but after closing Studio and reopening it, I now get the Error message immediately so it won't even open. Since there are no words in the Error message, I'm a bit stumped! I think I caught the words "not responding" flashing up at some point. Any advice would be gratefully received. Thanks! Helene
