New bugs found

After using a while ( live website ), I have also discovered some issues. First of all, the purchase code check doesn’t include the Item ID means, I can register a product with another license.

Example, I have two products: Product 1, Product; Licences: License1, License2

I can activate Product 1 with License 2, it shouldn’t be possible – in a another way, it’s required to add “ITEM ID” to the source code as well as need to check with Envato API if it’s the correct one.
