@jreidinger: it could be changed to 

```ruby
    _("If you do not register your system we will not be able\n" +
     "to grant you access to the update repositories.\n\n" +
     "You can register after the installation or visit our\n" +
     "Customer Center for online registration.\n\n" +
     "Really skip the registration now?")
```

Is that better?
