Risen - ModStarter 1.3.1.3 (Online DB version) file

If you already have old version of RMDS installed, then you must uninstall all currently installed mods from mod-starter and then uninstall old MDS too. Or if you already have many mods in your mod-list, then you can just install new version in the same folder with old version, after what you will have new RMDS with your mods in the mod-list.
