MinimServer 0.8.5.3 available from Synology Package Center

Depending on how you did the uninstall and reinstall, MinimServer might be doing a full rescan on startup. This might take some time and your files would not be accessible until the rescan has completed.

To check this, click the MinimServer icon in the Package Center and click the blue link under "URL". If MinimServer is running, the MinimServer status web page will open in a new tab in your browser. If you can see this page, what does the "Media server status" line say?
