Good morning, I purchased a START11 5-pack license from your FASTSPRING reseller in March 2023, this is the invoice number STARDOCK230310-2264-62817, I had to reinstall Windows 10 due to a system problem. I can't activate the product because it tells me invalid license and email. I contacted technical support and received evasive responses without any resolution of the problem. You're not serious, it's a shame, the product is really good.
