kaimei19 Was your keyboard stuck in the file transfer mode with no errors? It should timeout after 3 sec of no response, and In case of any error or timeout it should attempt to exit from the transfer mode.
To me it showed an error but it recovered from it.
I tried to transfer this file through Musicsoft and it said the filename is too long. By trial and error the max allowed length seems to be 50 characters including the extension. Shortened the filename and it seems to work now through the site. There was one another file in the database with too long filename, corrected it as well.
Will make a note to not accept files with filenames longer than 50 chars.
Thank you!
