disconnect.rb error messages

gistfile1.txt

Thanks a lot for this code. I tried to do a bulk download of all my activities from connect.gamin, but I get this error message:

vdO:downloads hvdosten$ ruby disconnect.rb –user=hvdosten –output-dir=garmin
Enter your password: ******
Loaded login page.
disconnect.rb:58:in `block in login': undefined method `[]=’ for nil:NilClass (NoMethodError)
from /Library/Ruby/Gems/2.0.0/gems/mechanize-2.7.3/lib/mechanize.rb:442:in `get’
from disconnect.rb:55:in `login’
from disconnect.rb:103:in `’
vdO:downloads hvdosten$

I would be very happy if there is anybody out there who could give me a hint how to overcome this problem. Thanks a lot in advance!!
