Can't access wp-content/themes dir in WordPress

Hi there,

I am hosted by Domain.com. I am trying to install a third party theme – vostok. I have read as much documentation as I can find as well as searched various support pages, but can’tfind the answer to this question.

When I go to upload the theme in its zipped form, I browse to it and hit upload, and the browse link just dissapears and nothing happens.

I then tried to FTP into the …/wp-content/themes folder. but I can’t create a new folder or move anything into the folder – upload, create etc. greyed out/no permission.

I can install a new theme from the WP gallery and it appears in the …/wp-content/themes, so I seem to have the right directory, I just can’t get the vostok folder into it!

Any suggestions much appreciated.

Cheers
