Thanks Amra, the MAF error resolution in the thread you provided was quite self explanatory so I'm downloading CFF Explorer and will have a go at modifying the "Vista" exe files. Should be fun!!

Hopefully Vista will handle physical and virtual memory allocations better than XP !?!
Its actually good as i've wanted to modify some exe header in the past and didn't have a tool available (I haven't done machine language programming for many years now). Will let you now how it turns out . . . . I've got a week off so even if vista dies

I have time to fix it.
