Sometimes when you create a new project in CodaKid Project Manager there is an issue in building the project and the files will not be placed where they will need to be. This could mean that nothing appears in the Package Explorer in Eclipse or a folder appears, but it can not be opened.
If either of those situations are occurring for you then please go to your CodaKid Project Manager and create a new project. Once you have made a new project, open it up and see if the files are where they should be in Eclipse.
If you have a folder labeled MDKExample instead, then that is fine as long as it opens and has the correct files inside of it.
If you are still experiencing an issue, just reach out to our support team and they will be happy to help.
