I recently purchased the software and cable from the Romanian provider on Ebay.
Had "operator" problems installing on my computer. I contacted the seller and he provided some additional instructions, still didn't solve "operator "problem.

I contacted him again and he spent three hours ( due to a slow connection ) via Teamview, software where he took over my computer and installed the system, it works great.

I can't say enough positive about this seller. He has a great product and wants it to work when you buy it.
