I'm pretty sure they all just stopped playing. Mojo, Jig and Almog were quite a bit older (mid 30s-ish) and they already only rarely played by the time Dr was formed. Blaze was just starting college at the time and was discovering his incredible gift of getting drunk from only 2-3 beers. With a sweet frugal liver like that, he probably never touched a computer again. Especially since his old mates had already left.
