issues with Mr. number call block

[MB64]

I've had Mr. Number call block for some time now and it has worked pretty good...except for the texting option....I have checked the option 'also block texts" and they still come through....no biggie though since its only one annoying person that texts..my issue now is that I switched back to the 9000 from the 9700 bold and 9300 curve..and now this app does not work...calls keep coming through although they are on my block list...does anyone have this problem?? I just tried using it another way, adding "all numbers beginning with" option....but I'd rather just put the numbers in separately instead of using that method....
