General Problem with the JW Player

Hello, everybody!!!

I am experiencing huge trouble with the JW Player right now.

Internet Explorer:

The FLVs on my website do not play at all in Internet Explorer (latest version, latest Flash) on most computers.
( http://www.aplusb-hides.de )

On other computers they sometimes play for a while - but when you
choose another video it does not play and coming back to the first one: it is gone as well. It shows a black or a white frame instead.

Then other some people can watch everything.

It is also strange that with changing the code (which had worked well for at least a year!) with the Setup Wizard I can make the FLVs appear again - unless I choose: autostart: true. Then: Blank / no FLVs!

Firefox:

Everything concerning my website is fine.

But:

I have noticed, that the longtailvideo-site plays with no videos at all
(while they do appear in Explorer on some other computers)

So: is there a general Problem with the JW Player at the moment????
Did you change some codes?

Did anybody else experience troubles like that???

Thanks for help and feedback,

Tobias
