Key State plugin not showing

Hello,
I'm using Truelaunchbar (latest version) on a windows 64-bit PC. I'm using the standalone version. I installed some plugins and all of them show in the 'New' menu and I can add all plugins except 'Key State' plugin which is not showing in the 'New' menu. I checked the plugins folder and Key State plugin folder is present with all the required files including the .ini file.

How can I fix this issue?

Thank you for reporting. I've updated keystate plugin files. Try to remove plugin using TLB Components Manager and install it again.

This is also the same problem with the System Monitor plugin.
