I recently purchased Vegas Pro 18, and registered my serial numbers with my account on MAGIX website. I followed the instructions and installed the products that came with the package. When i go to launch Vegas Pro 18 i quickly get a message stating Error code: -5 I do not have a license to run this application. I cannot seem to find any fix for this anywhere online, nor can i find anything about this error code. There is no place which i can find for me to enter in any information about my product code or serial number into the application Vegas Pro, only on the website. Ive tried reinstalling the products again, but i got the same out come. Any help would be great.
