Hi
well, the disk was not full...that is for sure....
The problem continued. I ignored it and when later in the day I had closed the computer and opened it, it worked. Today, I tried to open an old file (4 years old) and the software does not respond. It did not opened the file and since then it keeps loading without finally opening.
I will try later on again. But have in mind these issues related to the new version.
