DW9 quits when adding Spry Menu elements

Using version 9.0 build 3481 on a Mac G5 tower (2@ 2GHz). I inserted a Spry Menu Bar (vertical). Adding the first few items went smoothly, but now when I add any items, DW "unexpectantly quits." I've posted the work so far HERE.

Tried repairing permissions and clearing out machine caches, but still crashes.

Any suggestions??

Thanks,
