Productive Computing Change Prtinter Plugin - Need help

[Per Lind]

Hi All,
I have a hugh problem:
I'm still working in FM 5. It works very well at Windows 10.
It is a backoffice program for travel agents with a lot of automatic functions. My registers are very large and full with fuctions so I dont have money or time to migrate to a newer Filemaker version.

All my plugins work well except Productive Computings Chgange Printer Plugin.
It start and work well but sometime between 45 min to shut down Filemaker it stop to work. When I shut down I got a messeage that the "Plugin stop to work after 45 min. Please Register."

After registration the Plugin thank me for registration but still come the messeage when shut down. I have the feeling the plugin work much longer than 45 min, but I dont know how long time.

If I look at the Regedit I got following messeage:

(Standard)  REG_SZ             (No value)
cd                REG_DWORD  (not valid 32-bit value (DWORD))
Name          REG_SZ            Per Lind
RegCode     REG_SZ           60398720
Version        REG_DWORD 0x00000002  (2)

Does any of you have any idea why the Plugin take away all registration information in the Pluginfields registration and keep them i regedit?
Could someone help me?
Does any of you have an old FM5 Change Printer plugin who work, with a registration, which I can buy?

Thanks in advance.
