That's especially odd, as it last had a patch on the 23rd of last month. Is it the 1.4006 App / 1.4007 DB version that says 23/07/08 in the title bar?
Just to check, but have you inadvertantly set it to Level-Up mode rather than dynamic? In level-up mode it'll not allow selection of any higher level powers until you've selected the levels below first.
