Driver Studio 3.2 hang-up on WinXP

I installed new ICEEXT 0.66 with DS 3.2 support and it told me that some value in registry was wrong with SoftICE and if it should correct it and I said yes and now SoftICE starts without hanging up.

But now when I enter "net start iceext" at command line to start ICEEXT it tells me a "system error 1450" with a message that I don't have enough system resources to execute the service. this also happens when I enter this and SoftICE is not alraedy loaded. Then it loads SoftICE but for ICEEXT it gives me same error message (not ICEEXT message but Windows messge). But all my memory is free so this can't be. Has anybody seen this alraedy is is this also a problem of SP1 with all updates?
