Maybe you can try v2.0.3 at http://ipt.gbif.org using the following account: palanisamyg@ornl.gov / password

I just tried it using the attached zip file and it worked fine. 

Indeed there is a 100MB limit on uploads right now. Usually if a user has a larger file, we recommend it be broken into several files that get uploaded separately. These then get combined during publishing. Provided the file uses DwC column header names, auto mapping is done of course. 

Please let me know how you get on. If you want to send me the archive so that I can take a look feel free. 

Best regards,

Kyle
