Hmmm, those look more like hosting type errors on your server so I would ask you hosting company in the first instance. But, i'm happy to look further if you would please post your URL, superuser id and pswd in the secure tab of your post.

Sorry but I can't access frontend of backend - I just get a server500 error?
I also notice that your subscription has expired - support does require a current subscription I'm afraid.
What joomla component did you install/uninstall then that triggered this?
I would check your files with FTP too since there is a possibility that you have been hacked?
