directory).

Please include a log with any technical problem or bug report, it can speed up solving of the problem.
On Android, it's located in ‹Storage›/Android/data/jazz2.resurrection/files/Jazz2.log
or in Android logcat. On Windows, you have to start the game with parameter /log

I cannot access ‹Storage›/Android/data/

‹Storage›/Games/Jazz² Resurrection/Source/
‹Storage›/Download/Jazz² Resurrection/Source/
