WHDLoad crash on my A600

[Amigaz]

My Whdload installed games starts/works perfectly after Whdload v16.2 is freshly installed but after a reboot none of my games start and I just get the usual black screen with the red text "software failure blabla".
Never had this type of problem on my A1200 this thing has started to happen now when I've started using my upgraded A600 which works perfect with all other applications.
Does anyone here know what is changed when I reboot and causes the Whdload crash?

info on my my A600: 3.1 rom, WB3.1, 1mb chip, 8mb fast, 030 @ 42mhz.

Have a big heatsink and my case is fan ventilated thru thr top.
No heat probs here I can asure you
It's an Mtec card.

This thing happens on both warm/cold boots.
The crash occurs when I start the game from WB.
Don't know what tooltypes or config file I have Workbench 3.1 is just installed without any mods and Whdload v16.2 is also just installed without doingf anything further.
I've just started to learn some of the fundementals about Amiga's after been away from them for 11 years and when I had Amiga I just used it for gaming which I regret now.
