Hi and thanx for your interest in my problem!
… no, there was nothing like an error report, the app just doesn’t start…
… and yes, I uninstalled and reinstalled both, the Kurviger Pro and the Kurviger sharware version, no changes, both do not start at all and do not give any messages …
When I downloaded an older Kurviger shareware APK (Version 1.6) and installed it, it worked flawlessly.
It would be ok for me to have this old Pro version running for a while, but 1. it doesn’t solve my problem and 2. I don’t know where I can get the Pro APK Version 1.6 .
Last but not least I can’t definitely say, which version I had before the last update of Kurviger Pro (1.7.3), but the version I had worked fine in January, so I gues it has something to do with the last update version of Kurviger.
