Ibrahim,I have found and resoved the problem about List All Downloads failing to truncate the description. It was also happening in the List My Downloads menu.They are both fixed in the fortcoming jD 3.9.8 release
Which version of jD are you using? If you are using 3.9.7.3 I can send you a replacement file for each item. It would mean using FTP to overriite existing php files so best if it is a test site.
