I just installed the updater extension that checks if your extensions are up to date.

My Sliding Panels needed to be updated.

I did the install but its telling mey serial number is invalid.

I went to my products, pulled the serial number from that page, pasted it in.

Still getting the error.

Tried uninstall, re-installing, rebooting, clearning dreamweaver cache, still getting the invalid serial number error.

Hello Dean.

I see currently that you are using subscription.
You need to use the serial provided for the subscription for all extensions. When the subscription expires , you will be able to use the extension with the serial provided for the purchase.
