Red Screen in RUSH

I am new to the community and just installed the free version of RUSH, I want to test it out before I buy. All I am trying to do is edit an iPhone movie with minor elements! The clip was uploaded to google drive and then downloaded to my mac.  It plays fine in Quicktime and has the .mov extension.  

I have read through all the other comments and done the following:

• Unchecked "Enable hardware acceleration..." and restarted my mac
• Uploaded the video to my creative cloud
• Synced my creative cloud - it plays fine in the cloud!
• Added to RUSH from my creative cloud
• Created my project anyway with the red video (audio is fine) and exported
• Exported project still has red screen for video

What am I doing wrong - what else can I do to fix this? 

The only reason I'm trying this out is that iMovie does not allow me to change my aspect to 9:16.
