Unable to Install/Update Addons

[Xyltin]

The Update and Install buttons next to the addon's name doesn't work. I can click them, but then it will load forever.

The Install button at the top right side of the addon description does work to install them.

The Autoupdate function has the same problem as the Update button. It will load forever.

For every update I have to uninstall the addon and re-install it with that button in the extra window.

Restarting Minion doesn't change anything.

Using Win7. Can't upload .log files, so i added .txt
