When updating plugins, you must delete any previous version from your project first.

This is mandatory since Unity's package importer system doesn't delete or rename existing files so any old scripts that aren't directly overwritten will cause compile errors that prevent anything from working. Check the Change Log to find out what has changed between versions.

Note that the performance of the Full Version is significantly better than the Demo as explained on the Benchmark page.
