Thanks for the reply.

Well, following what you said I inserted these two lines in my .vmx file:

mks.enable3d = "TRUE"

svga.vramSize = 67108864

(actually the first line was already there but was changed from FALSE to TRUE).

Now, at least Joost starts up without any error messages. However, it is still not watchable as it is so incredibly slow.

I'm surprised at this as of the 5 criteria that Joost lays down for a configuration consistent with Joost, the only one my virtual Windows XP had failed on was the graphics card memory. Additionally, our broadband connection is not the problem as we have Joost on another computer working perfectly off the same router.

Are there any more cards up the sleeve that I can use to encourage my VM WinXP to use Joost?

Thanks

Paul
