[TYPO3] Could not fetch translation status

[John de Stigter]

Hi all,

I'm having trouble with updating my language files. When I click "Update
from repository" in the Extension manager only a few files are updated.
But for a lot of extensions, for instance "sr_feuser_register", it says:
"Could not fetch translation status".

I am trying to impor the dutch language. Is this a problem at the TYPO3
server or is the translation not available in a new format?

Cheerios,
John
