If your load times are that large on your system you have something else going on in your setup as that is extremely atypical. Some things I would verify are:
Do you have a virus scanner active scanning the process, causing the process to pause while it's being scanned?
Do you have a file sync tool running on the folder that would lock the file, making it impossible for us to open it?
Do you have any third party apps running that alter/force video card settings on the application? (Things like NVidia control panel)
Can you run a CHKDSK on the drive LaunchBox is installed to to see if there are any bad sectors on your computer?
Can you open command prompt as administrator and run the command "/sfc scannow" (Without quotes) and then restart your computer and see if that helps?
Also make sure you're NOT launching LaunchBox as administrator as it WILL cause issues and make it hard for the application to find it's files appropriately.
