[Typo3] URGENT - reverting to the old tt_news

[Rainer (Rene) Suthoelder]

jupp, this behaviour is documented, but anyway:
go to the TER and select tt_news by clicking on its extension name. this 
will bring you to the extension details page where in the upper left corner 
you are able to select from a dropdown menu older/previous versions of 
tt_news.
but i don't know if it is possible to switch back to an older version 
(perhaps the db was altered...).
you could also try to describe your problem in the typo3.projects.tt-news 
NG, perhaps someone there can give you a helping hand.
