The export functionality did not exist in any ProPack for SLP version 3 so the answer to that part is pretty simple, No.
It is not advisable to run old versions with new . Mixing some versions (like 3 and 4) is like oil and water. Is there a reason why you would not update the FREE SLP base Plugin to the current version?. Before you do, again read the troubleshooting guidance about the steps to take. SLP version 3 is no longer supported nor would it have any of the updates and/or bug fixes, security patches if any etc. SLP is now on version 4.4.17. (see release notes) WP is also on version 4.4
