Lightburn and laser (Thunder) has been running the same file for weeks. I continue to add designs to this file as recently as last night. This morning upon attempt of opening this file I received the error " Project file warnings: - LightBurn 1.7.01 Expected ‘[a-zA-Z]’, but got ‘.’.(line 50967?) and now it is missing weeks of work! I have not attempted opening any other file for fear of losing data. I have also emailed lightburn support. Please help!!!
The way you’ve phrased the above makes me believe you’ve been doing weeks of work in the same file - is this the case?
Are you using Google Drive, Dropbox, or similar to save your files to a cloud/remote server?
That is correct. I have been using the same Lightburn file and just building off of it for my vendor markets.
Unfortunately no, I have not done a recent backup of my files. The last time was back in September, so do not have up to date files stored elsewhere.
