MinimServer not working

[Bart]

Have you tried this (the part in between the ***) from the MinimServer documentation?

Online updates

From 0.8.1 onwards, MinimServer and MinimWatch can install online updates without needing to do a download and reinstall. When a new update becomes available, you'll see a pop-up dialog informing you about the update and asking if you want to install it. You can install the update from this dialog or you can ask to be reminded again later with another prompt. The reminder interval is 1 day by default, and this can be increased to a maximum of 30 days by setting the .updateReminder property. ***At any time, you can use the About dialog to check whether any online updates are available. After installing an online update, you need to select Relaunch from the update dialog for the update to become active.***
