Hi Andy,

There is a patch available for version 2.0e that corrects some issues.

As to whether or not to upgrade, only you can decide if it is worth the cost.

I am not a professional graphic designer but I upgrade because I love the program and enjoy using the new features.

In regards to Flash or SwishMax, I find SwishMax easier to learn.
