i also can't get the webserver to work. always either some general unexplained "problem connecting" or "file server will not allow any additional users", which doesn't make sense as there are no users. this has never worked for me. i can do the itunes transfer but i don't like this bulk dump approach.
the wifi access works beautifully in goodreader on the same device (and always has), so clearly the issue lies with comic zeal. wish this and other applications would follow goodreaders's file excellent management model, it is hands down the best on the ios marketplace.
