Hi there,

"We have released a brand new launcher. Please download the new launcher from https://stackideas.com/dashboard";

Regarding this issue, this is because we have do some major change on our latest version and it is required for you to download a new launcher and install it instead of using "update" button. We have announce it at https://stackideas.com/blog/easyblog-5-0-38-and-easydiscuss-4-0-9-updates as quoted

Also, along with these updates, we have improvised the usability of setting up EasyBlog and EasyDiscuss so you will need to download the new installers from your dashboard to install this new release. With the new installer, you no longer need to enter any API keys. It will and should work out of the box.

Please give it a try and see how it goes. Or maybe you need help regarding this issues, can you provide us with your back end access in order to update/upgrade/install it for you.
