Please carefully review the AppWorld catalog page:
Be sure that you meet ALL requirements, including country and carrier. If you do not, then that explains the result you are presently seeing. If you do, then contact your mobile service provider for formal support.
Note that I cannot answer as to why you may have earlier had access to the newer BBM...I have no idea why, but I know that the requirements are solid.
