Sorry, I am afraid that I am out of idea.

But can you confirm the following two things:
1. After installing MagiKB, have you selected a key-mapping file. By default, no key-mapping is selected after the installation. You should select or modify a key-mapping file.
2. Is there a file named "MGKBLS.lnk" under folder "\Windows\Startup". If not so, open the options window of MagiKB, and select the autostart option.
