errors and unable to make videos in rush

Have been paying the premium price for 5 years for adobe creative software. Why is there not an update to correct this issue ?! I cannot upload videos to rush and it will not allow any new videos to upload- every time I receive an error message that the videos are invalid- along with a multitude of other issues like crashing and inability to make longer videos / this is the way to lose customers ! How do I get a refund for the months that I have not been able to utilize the app ? I see people trying to ask the same question in the community page and no one has a response or answer for them. -                   - I appreciate the help and response from the team at adobe  - hope  everyone is doing well and Inspired by the future /
