Hmm, I don't have CS2 to test. Can you please comment out the code on line 311? Just delete the line or add //
to the start of the line, like this:
//imagesDirPreview.maximumSize.width = 260;
You'll also need to do the same with line 319:
//jsonPathPreview.maximumSize.width = 260;
If you get a new error after that please post it here.
