[MiKTeX] Problem after updating Mktex

[Per T. <pe...@gm...>]

Hi,

I have been using Miktex 2.9 with no problem. After updating today, YAP does
not preview my files and shows only a gray window instead. When I set my
Miktex system to 2.8 (through Winedt) I can view the dvi file alright. I am
wondering waht has gone wrong in the updating process.

Thanks

Per
