can not open gbb - files
I'am working with geogebra classic 6 in desktop-version on a Windows 10 . My question has been asked several times before, but there is no solution in sight.
I have created a file, saved it with download as a local file. I can reopen it with no problems. All my other ggb-files that I created afterwards can not be reopened. A message "Loading" occurs and nothing happens.
I'am new to the forum. Can anybody give me a hint or check the attached files. xy1.ggb opens, xy2 does not open.
Sincere thanks for every hint.
