Have you run a full DRC and made sure that there are no conflicting design
rules. I have seen this in the past when there were design rule issues that
made the board unroutable. One thing in particular is if you have no keep
out defined in which case the router can't find the edge of the board.

Subject: [PEDA] Protel 99 cannot auto-route BGA components
I have been unable to autoroute a 10 layer design which has 2 fine grid BGA
packages. Protel support has not been able to assist me and has cause a 3
MONTH delay of this design. Protel's auto-router simply locks-up or does
not initialize. The autorouter give no reason for the problem and Protel is
either unwilling or unable to address the problem. Therefore, I am under
the impression that there is a major software problem with respect to the
autorouter and BGA components. Has anyone else seen this problem? If any
other user has had this problem or know of a fix, PLEASE contact me
([EMAIL PROTECTED]). Thanks you for any feedback.
Loop.
