Transfer Failed??

Every time I try to Upload Direct, it says transfer failed. I really have absolutely no clue how to stop this :cry: Please help! It says I have forbidden characters in the file name but I don't and No such file or directory but that doesn't make any sense!
Connection log is as follows:

257 "/Portfolio" is current directory.
