Hello John,

I know this problem is resolved as you submitted a support ticket. As described in the Knowledebase, the Run-Time Error 9 Subscript out of range occurs when trying to unlock APDL v6 on the Palm OS with a version 4 or prior registration code. Contact sales (as you did) to obtain the version 6 license code. This response is for others to learn from should they have the same issue.
