I have been running version 5.3.1 on a Community license for 3 years and have some big databases set up. I have no idea what happened but somehow my entire Stardog folder was updated to version 7! I can't run it because I don't have the right license. And I don't want to lose my databases. I cannot imagine what happened. I did update Java using apt-get update about that time, but that shouldn't have pulled in Stardog. This is the strangest thing I have ever seen in all my years on Unix machines.
Anyway, I have no idea what to do now. Is there any way to backtrack to 5.3.1? I don't have the original download files, unfortunately.
