4.7.1.0 won't start on DS216play / DSM Version 6.2.4-25556 / Update 6

Hi there - I just installed the latest release version 4.7.1.0 on my DS 216play with DSM 6.2.4.-25556 Update 6 - and it won't start after installation. Manually starting also fails. Upgraded from Version 4.6.7.0, which installed and ran without any probelms. I tried deinstalling and installing from new - also fails. Now installed 4.5.4.0 which again installed and started without any problems. Any ideas? Thanks!

Hi, are you able to update to dsm 7?

I could, but don't want to for I would be losing usability of other apps.
