I did some editing in protools for about 20 minutes with no issues and then recorded midi and audio for 20 minutes, also with no issues at all
So, everyone who has ever had this issue (and it looks like many, many people, judging from the amount of pages typing "MBox Pro flashing blue power light" into google returns!), see whether your fire-wire cable needs replacing. It worked for me.
guatamas, thanks for your tip re the order of booting up. I don't always do it in this order but will from now on


Thanks again everyone

Thanks for this quick fix! Had the exact problem and thought i had some really seriouse problems. Found this thread and got a new FF cable and
everythin works......
