Just got email with the new download links of R13.5. The archives of Android and windows version have a CRC error on MEGA.
Sorry about this, was made aware that there is a problem with the Mega files, the files were corrupted during the upload it seems, first time it happens to me.
In the meantime, 1fichier files works, will send fixed link for the Mega tomorrow. Shouldn't happen anymore, I'm switching to a folder system so if there is a problem, there will be no need to redo the links or resend something. Learned the lesson.
