Out of stock on virtual product with Jigoshop not managing inventory

Hello,

I just updated my clone/testing site to 1.10.2, and now I am unable to add products to the cart. I only sell virtual products, so I have Jigoshop set to NOT handle inventory. When I try to add something to the cart, I get an error like this:

We are sorry. We do not have enough “Hear God Through Your Dreams” to fill your request.
The Product could not be added to the cart. Please try again.

Because of a different problem I was having on my main site (which I just posted a new thread about), I was reading some troubleshooting instructions including uninstalling and reinstalling the plugin. I don’t really know the proper procedure for that, so I tried simply deactivating and reactivating Jigoshop on this clone/test site. I did this right about the time that this shopping cart error started. Might that have anything to do with it? Is there a proper procedure for uninstalling and reinstalling Jigoshop that will not lose data or have any adverse affects?

Here is my System Information that I just posted in another thread:

Thanks.
