VE Freezes while rendering WMV

[PrayeR]

Hi all,

I am working with Ulead Media Studio 8 to create WMV video's for the web. Because i make a lot of video's i use the batch (create multiple file) function often. Only problem lately is that it freezes most of the times after it has rendered 2 or 3 movies.

Also when i edit the movie VE freezes often.

As input i use 2 AVI movies (640x480, approx 600MB total) that i edit into one movie (approx 30min). I render this to a 320x240 WMV file and a 640x480WMV file.

Can anyone help me with this problem?

Regards
