You should be well within their USDA range, and cold shouldn't be a big issue. Just in case, this article will help:

This resembles something a little more sinister. It looks more like a disease called "sudden vine collapse". This is typically 1 or more viral infections simultaneously. This can present itself in a number of ways, including the leaves being left on the vine once dried.

Those need to be removed. After that, I would send samples of the soil to one of your closest horticultural extension services. This will help you find one:

After you find out which of the diseases, if any, that the vines have, you will want to solarize the soil to help kill off most of what is in the soil.
