Odd. Version 2 software should be entirely not-flakey. There are a lot of issues with version 3, but 2 should be solid as a rock.

If you were having trouble with it, I'd be concerned about other issues, such as hardware problems.

My opinion: You should get version 2.0 working stably and fix any hardware trouble you might be having, before trying alpha software. Multiple unrelated failures tend to cloud up any troubleshooting process.
