In most case, the problem is a problem of network, try re-installing it for one or two more times. Another solution is to manually upload the module via FTP of cPanel to avoid having network problems.

If you find the file, which you are going to editing, having empty lines after every line of code, then don't edit it or upload it back to your site. The problem is probably due to your FTP clients or your server settings, please Google for solutions. An alternative way is using cPanel to zip files before downloading or uploading them to avoid having problems during file transfers.
