CRM Package installation problem

Hi Gurus,

I am trying to install SAPKB70010 (SAP_BASIS) software component on CRM 5.0 system. During installation SPAM got aborted and I have deleted this package from PAT01, PAT03 tables and tried to reinstall it from scratch. This time i am getting weird problem. When I try to run SP_MANAGER t-code ( special support package manager for CRM), i am getting "Package is unknown." and when continued, "Internal error of SPAM check". have you guys ever come across this problem. Please help me to resolve this issue.

Thanks,

Raj
