I am not able to upload my file on easyfileshop tab in edit page (admin section)

Hi,

I followed the instructions, after completing the settings, I moved to edit page where I wish to put the buy button. But in admin section the easyfileshop tab is present but its height is too small when it is expanded. Thus am not able to add my digital file on it.

Please help!!!

Thanks,
Savaratkar S
