Error uploading to modhistory

Hello! I just tried an upload to modhistory and got this error:
[phpBB Debug] PHP Warning: in file /var/www/modhistory/mmh/includes/processors/upload_file.php on line 13: rename(/var/lib/modhistory/mmh/content/uploads/files/ringcapabilityshop.rar,/var/lib/modhistory/mmh/content/checking/holding/ringcapabilityshop.rar): No such file or directory
Failed to move the file!
In addition, when I tried to submit this via the "contact" link, the submission button on that form did not seem to do anything. (Not sure if this is same problem as previously reported in another topic on this forum).
Edit:
Here is the mod on Sendspace if someone else can put it on modhistory: https://www.sendspace.com/file/xls6ij
