Critical Path and Gantt Chart help

My university has set up ProjeQtOr and hosts it, allowing us to access it via a provided link. I have previously explored installing it myself and believe I can make my computer the local host. Apologies if my terminology is not accurate. To get the latest version, I will need to install it myself since I cannot dictate my university’s decisions. When I do this, I would be happy to export my project file (if possible) and share it with you so you can review the data and identify any obvious mistakes?
