I just installed Spark 2 and it looks unbelievable. Can't wait for final release.
Anyway, I installed it in separate folder, I hoped I would be able to run old 1.7.2 as well as 2.0 Beta, but unfortunately after installing Spark 2 Beta into separate folder, my Spark 1.7.2 won't launch anymore. After starting it, I get a message "Spark.exe has stopped working".
Spark 2 Beta runs fine, apart from one crash that I experienced when trying to load one project. Next time I tried loading it, it worked fine.
Another question... how does this Beta testing affect our license? Once Spark 2 goes Gold (out of Beta), are we going to have to enter all those information again, or everything is done automatically?
