What should I do when my access token expires?

What should I do when my access token expires? I received an email to update the AliExpress Dropshipping plugin. After updating the plugin, I started having problems importing products using the Chrome extension. I reinstalled the plugin that I initially purchased and it worked. That’s when I noticed my token had expired. I went to the Villa Theme’s support but my support had expired as well. I purchased support, but I still cannot access the replies. How do I get another token?

Thank you,

Marcus
