Purchased Vegas Pro 20.0 in August. Been using it with great success since. Came into my office today and tried to launch the program and the activation popup launched. I verified my serial number and it came back as unable to activate "serial number invalid or related to another product..." Checked on the other PC we have the same version/serial number of Vegas installed on and received the same error. This is totally out of the blue as it worked earlier this week. Not sure what to do. I "contacted" support but was greeted with an flabbergasting 2-4 day wait before a response. Not sure how to move forward with business with our software down and such a long wait time for support. We rely on Vegas daily and have deadlines on projects 95% built in the software. Any help would be HUGELY helpful!!! Thank you in advance.
