Can you provide more details regarding the problem? What do you mean by "cannot open any of my old projects"? Not clear why it asked you to remove them from the list.
If you want to open an existing project that is not on the list in the Projects tab:
- goto the Projects tab
- select the green button at the bottom left (Open an Intel XDK Project)
- navigate to the directory that contains the project you want to open
- select the <project-name>.xdk file in that directory
If your project needs to be upgraded, you need to select the "Upgrade" button in order to upgrade that project (use your mouse, do not hit the "Enter" key). If you select "Cancel" and then select "Remove Project" your project will be removed from the Projects tab list.
