Cannot install EasyBlog

Dear sir,
I have purchased EasyBlog Extension yesterday and I do not manage to install it.

I am using Joomla latest version 3.2.1.
When I try to install the extension from the Extension Manager I get the following message:

Error
There was an error uploading this file to the server.

I also tried to upload the extension to the server and install it from there - Still no success.

Please instruct me how to install the extension properly.

Regards,
Shira Grafit
