While working on my major course assignment, the message 'License is not valid' suddenly appeared. and also, License key required, you exceed the size limit of the free version for this file type, design is stored in different file format!
-> Full Version of the LayoutEditor required to store design in selected format. Design exceeds maximal size possible with the free version.
1 Design will be saved in LayoutEditor cloud format (.lec) instead. Opening will only be possible on this system or with our cloud services.
What I am currently working on is a major course assignment that must be submitted later and This assignment involves implementing a TFT-LCD display pixel for a display panel and is strictly for educational purposes.
Therefore, I would like to know how to resolve the license and size limit issues.

Do you have a license key installed? If so, please let me know the license id number via support@layouteditor.com . The error message 'license key not valid' with an additional explanation can show up if you installed an update and you do have a maintenance for your license. In that can, please reinstall the release published during your maintenance period.
The mentioned size limitation will only show up with the free version, without a license key.
