XF 1.5 Error when upgrading to 1.5.8

#1
I get the following error when upgrading from 1.4 to 1.5.8:

Invalid class: XenForo_Route_PrefixAdmin_Languages

Upgrade will not continue.

This would generally indicate that at least one of the files hasn't been uploaded properly. Please reupload the files.

This is the same underlying cause. The fact that you seem to be getting different errors at different times definitely points to upload issues.

Please submit a ticket with FTP details (and a user login we can use to access the upgrade system).
