The new IF2 for fickpack2 in the Client seams to mess up the locally installed plugin in the Designer client somehow. But there is an easy fix to that.
Close down the client and navigate to the workspace\applications\eclipse folder and delete everything in it (You should probably make a backup before 😉 )
restart the designer and go into File – Application – Install
Select the “Search for new features to install” option and click next
And when you get the next page all you previous plugins should be there and you just click “Finish”
Now the fun part begins by accepting all the licenses. But when that is done and your client is restarted all you plugins should be back.
