I bought Vegas 18 Pro back in March. Used it successfully. I want to make a video today (December) and it wont allow me to drop in a video or open an older file. it just keeps hanging up.
Im a bit new to this so please help me understand what im doing wrong
Try updating to the final build. https://www.vegascreativesoftware.info/us/forum/vegas-pro-18-update-5-build-527--129047/
If that still doesn't work, do a reset: https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-reset-vegas-pro-to-default-settings--104646/
Also, when you do get it open, go to help/driver update and update any GPU drivers.
