Quote from uexkuell:
Today, login (with the old standalone version, which I sure will update now) is again possible.
Therefore possibly/probably some problem aside from the version alone.
(Just to remind: everything worked with the download-version yesterday, in my eyes this makes clear, that it is not a problem with my connection or the general software configuration on the computer aside from TWS/Java)
This "old" version is 894.4 from May 2009 (this is 5 versions back from the current as far as I can see).
I leave it to your judgement whether this is a "rather old version".
I think, if MSFT wouldn't further support their data formats 6 months after issuing a new version of "Word" even they would have some problems with their customers.
