Two last updates caused the so-called FC (force close) issue with the app. Got a lot of compains, really sorry that happened. We just found the reason and will roll out update in a while. The problem is with the latest update of the software we use to create programs, the IntelliJ Idea 11.
If going into technical details, it built the application slightly different from the way it did it in previous version, thus causing some errors when using the app. The update will come soon. Sorry for inconvenience.
Update: it looks like the JetBrains (producer of the Idea 11) was aware of the issue and created a patch update yesterday night :)
