Welcome to GPLDL - we are still beta - please report any bugs via the contact form.
:-) Good luck
Just been notified this has now been updated to 5.4
Very quick in resolving this problem once I mailed the gpldl team.
Version 5.4 was listed as part of the latest update 17th July, but does not appear to have been updated in the repository. I am hoping it will be updated soon as thge current version is not compatable with the latest composite product version.
