Thanks for your input. We just released 6.3.80 and we are VERY happy to say that MediaShout 6 is EXTREMELY stable. It does not crash for no reason. If it freezes or crashes, there is something else that is causing this. Yes, there is definitely a learning curve. But, we do feel that the changes are for the better. The more you use it, the more comfortable you should become with it.
If you're willing, reach out to me directly and I'd be happy to look into the issues that you seem to be having. Ryan@MediaShout.com
