I am using SoftICE 4.30 on both my laptop and my desktop, using the Universal Video Driver. Both computers are running WinXP SP1.

I had problems while the start mode for SI was set to modes other than Manual. Set your start mode to Manual, then once in Windows, start SoftICE yourself, and see if that works.

Also, it wouldn't hurt to get the SI 4.3 updates from CompuWare's support page (hxxp://frontline.compuware.com/nashua/patches/).
