I’m sorry to hear you’re having issues. It seems like you’ve installed the program over a previous installation. This way it will just patch himself back to a previous version and won’t open any older files, which makes it unable to run. You will need to make a clean install, and uninstall the program first. If you would like to downlad and install every package manually, here are the download links for your installation:
As for your second note, it seems the program didn’t recognize you pressing ENTER, as it was implemented and tested to do so. We didn’t want to force anyone to install the update, and I’m really sorry to hear that didn’t work for you. Hopefully a clean reinstall will fix your problems.
Please let me know if you face any issues!
