2.9 FIRMWARE SAVING PROJECT ISSUE

i thought about the names too. couldnt see any special characters.
I suspect the SD Card did reformat again and have the same error.
With an older card i have no problems.

ok guys i found out one reason that may help , I notes when i named my project with the # symbol in it that it would not save properly , the project file was not made but when i used all letters every thing worked fine and saved with no problems . your welcome
