Problem with replying

[Xenon]

i often have problem when try to post a reply... often it tells me server not here or such an error....

sometimes i have to try it several times before the post is sent.
viewing the threads isn't a problem, so my connection is ok.

this error occures since a few days.
most of the time it works perfect, but in some threads there are problems, especially when i try to make a quick replay this error occures more often
