What's wrong sir ? i just upload version 3.7.6n
You basically need to go into your WordPress settings and increase your upload max filesize.
Depending on what you have got setup you can find the setting in either php.ini, .htaccess files or your own .user.ini file, then you can easily just update it through there by changing the current limit to something like 40m.
If you are unsure what or how to do it, simply search online for WordPress increase upload max filesize and you will get many results telling you how to do it.
Also, check what your own hosting limits are on their servers as in theory you could jack it up to something like 64m or double at 128m, however that wouldn't work if you have limits of say only 40m or lower yourself.
The other option which means you don't have to modify anything, is to manually add the two plugins into your own plugins folder in wp-contents and just copy and paste the plugin folders into there, don't add the whole zip files itself.
There are some plugins that will do this for you, however it is always best to do it yourself so you know how to do it.
