You've probably used it before so you may already be familiar with it. Essentially we need to make sure it is rendering it's error messages properly formatted (i.e. each line of the stack trace on it's own line). Right now they are all jumbled together. Might be as easy as inserting a <pre>...</pre> around the error message.
After you do that, I want to address some of the visual issues. The file boxes don't really line up very well and the button looks weird if I recall correct (has a recessed border around it).
Essentially, we want it to have a similar look and feel to some of our lookup screens regarding how the button looks (you can look at the Document Type lookup, Rule Attribute Lookup, Rule Template lookup, etc. for an example of what I mean).
