I really need help

Hi, I have to write a dissitation and I need to download a program from my university, using this program, but I cannot as in the box it says 550 Unknown directory / drive not ready: /A in red. I have followed solutions to all the known problems my university says sometimes occur, but they do not work. I seem to be connected to my files but the A drive has a cross next to it and so I cannot look at or download the files on it which I need?

This maybe a really easy problem to fix but I dont know much about computers!
This is what it says:
[13:00:43] PWD
[13:00:43] 257 "/A/ajh57" is current directory
[13:00:52] CWD /A

It would be much appreciated if you could help me as I need to download a program using this to write my dissitation! Thankyou, bigdunc
