Can't access database

 I have new computer for windows 7 64 bit. i want to install Accpac 100ERP 5.4A (this is free update version) to this new computer. i perchased database pervasive v10 for workgroup edition (because ther are 2 computer will use accpac).

i install pervasive ver10 first, then put activate code on license administraor to replace expired code that let me try for 30 days. i put 2 new fold under database folder that relate accpac. I install pervasive under C driver.

next i install accpac system manager, then do database setup. then install lanPak. i install accpac under C driver.

when i open accpac system manager, it shows following message:

administrative service is not active for this system daatbase. create adminstrative service data?  Yes proceed

then shows: pervasive license is invalid or has expire. Can't access database (error=96)

i think accpac may find out first pervasive code that has been expire but it can't find the new code OR MAY BE OTHER PROBLEM what can i do?

pervasive already has new perminent code and old code has beed deactive.
