The Lounge is not non- technical help. Please let us know what software you are using- i.e. Dreamweaver, Muse, etc... then we can move to the area that can help you.
Please try performing the below-mentioned steps.
This error might be triggered due to any unsaved changes to the .muse file.
- Unfortunately, in this case, the unsaved changes contain a problem which results in this error and the subsequent shutdown of Muse.
- " Selecting "No" will mean all the work since the last save will be lost, but the .muse file on disk could then be opened and worked on without errors.
- With the "Recovery" folder and the .muse file, we should be able to recover any unsaved changes and correct the source of the error (assuming you haven't already selected "No" when launching Muse) and return the corrected file to you.
Please follow the above instructions and see if your file gets opened or we can get it repaired if required.
