are there multiple files in the zip file? also try to unzip and then rezip the image, sometimes it's a non-standard zipfile image to create problems
No, the zipped file content only ONE .dsk file.
Example: cpm30a.dsk to cpm30a.zip
Also I rezipped the file several times.
If the zipped file is wrong, the disk will not boot.
It is booting but later come the error.
