My save button won’t click

I just bought the pro plugin of Aliexpress dropshipping plugin. Activated auto update. I have been using the free version for sometime and everything has been going well till I installed the pro plugin. Every since I installed the pro plugin, my save button won’t click. It just makes some sort of sign or stuff but doesn’t click. I can’t activate product synce, cause that’s the main reason I bought the pro plugin. What could be the problem??
