I am trying to get the program out of a 1756-L72/B Logix 5572 ver 21.11 with Studiio 5000 ver 24.00. When I try to upload, it changes to Studio 5000 Logix Designer ver 21.00. It gives me a screen that says "Connected To Upload" I click on Select File and give it a name. I Click on Creat Project File and Upload "Yes" and it looks like it is working, but when it finishes the screen looks exactly like it did before I clicked upload. I look for the file and find a .BAK000.acd, but it is empty. Does anyone have any hints of what I may be doing wrong?
