error 452 :S whats going on?

Smart FTP has worked well for me, apart from being a complicated startup I got it to work. However after using it, it comes up with this error and I am baffled.

I edit my pages, click save, upload the new updated pages and doesn't save! It comes up with this error message

[21:09:13] PASV
[21:09:13] 227 Entering Passive Mode (*****.***.***)
[21:09:13] Opening data connection to **.**.***.** Port: ******
[21:09:13] STOR faith.html
[21:09:14] 150 Opening BINARY mode data connection for 'faith.html'.

[21:09:14] 452 Error writing file: No space left on device.
[21:09:14] Transfer failed.

I have no clue on what to do, no space left on device ? whats going on there!

Well anyway this is my only source of money at the moment and would like some help really quickly if possible.

I have removed the i.p. address for security reasons and replaced them with ***'s

Cheers

The first thing you should do is purchase a license for SmartFTP because you are using it for commercial purpose. Then we can help you.
