Please use different name or version for paid and free plugin.
I have the lifetime paid version without the “automatic update plugin” activated. Due to the same naming and version of the free plugin, on the next update wordpress will update your paid version with the free version from wordpress public repo.
Thats really bad, cause your plugin is not working anymore, if you are using premium function.
My suggestion: premium version should be one major version higher, like free version is 2.5.5 and paid version is 3.5.5.
