Hello Shaon!!
Last year I installed Version 2.6.4 and today I pay for “DM-Pro-v4.1.1”.
but I see this massasge in the “Install Plugins”:
Installing Plugin from uploaded file: Download-Manager-Pro-v4.1.1.zip
Unpacking the package…
Installing the plugin…
The package could not be installed. No valid plugins were found.
Plugin install failed.
How I do this upgrade to pro version?
