That error is weird. It says it can't find a class called "Curlypublic". I don't know why it would even look for that... what version of vB4 is it?
I'll be testing the vB4 version of the script myself in a few minutes. I have to wait for it to finish uploading. I'm trying to figure out right now why it takes so long. It doesn't make sense for an upload of this size to take 40 minutes.
