Samsuite is a software supplied by MacroVision (makers of Flexlm license manager) which enables easy interface to the lmgrd license manager.
We found that it has a date limitation... If you supply your clients codes that expire after 2030, it would report that codes are incorrect and exit without starting the license manager.

The solution is to generate codes that expire before 2030.

It looks like Macrovision is on their way to fix this issue. Macrovision is retiring its suite of SAM products (SAMsuite, SAMreport, SAMalarm and FLEXadmin) after December 31, 2007.
Macrovision’s FLEXnet Manager will replace and extend the capabilities of the SAM product family.
