Toon Boom Harmony not showing any interface and options

Hey I’m new to the program and I’ve run into a serious problem. When I opened up the file I was working on it simply doesn’t show anything, the program is open and I’ve checked that the file itself is in the right place but all it show on screen is an empty window with only top bar with; file, edit, view, ect. selecting those options everything there is basically greyed out. I know it’s not a corrupted file because this happens as well opening new files as well.
I have shut down and restarted my computer already, I will attempt to reinstall the program right now but if that fails I would like any other ideas, thank you.
