Please specify in your email the following information for we could find your order: email address was used for purchasing, your license key, your order ID.

So not only was I unable to use this back when I bought it due to numerous issues that don't seem to have been solved over the course of the past couple years, but now I can't even attempt to use it again because the licenses only work for the current major version, and I bought it on version 6, yet you don't provide downloads of old versions, so I'm stuck with a license for a version I can't even get. What kind of ridiculous company is this?
