Hi Elbo,
From the logs I can see you are using one of our early products from around 5 years ago. While we do the best we can to maintain compatibility across the whole range of products that our customers have made with our technology, it's not easy to cover the entire matrix.
You may find that one of our earlier W7 release (e.g. 5.4) works better, you can download from here:

Can you post details of the other devices you have tried? The PIDS would be adequate, although a description would help too.
I hope you appreciate that the behaviour you are seeing is faulty and we don't ship software if it behaves like that in pre release testing! I think you are just unlucky and have hit an obscure combination, or else there may be a hardware fault.
