Using WP 3.3.1, cannot access dashboard anymore

I have read many other FAQs and posts on this site, but I don’t know how to fix my problem. I considered myself somewhat computer savvy until now.
That last time I edited my website was March 2015. I don’t use an FTP or shell to edit my website, I’ve always just visited https://www.echoesofchicago.org/wp-admin/index.php. But now when I visit that URL the menu options on the left side of the screen are there, but everything to the right of it is blank (see 1 in screenshot file)

https://www.echoesofchicago.org/wp-admin/about.php (it tells me I have WP version 3.3.1) (see 2 in screenshot file)

https://www.echoesofchicago.org/wp-admin/admin.php?page=jetpack (see 3 in screenshot file). When I click the “connect to wordspress.com” button it takes me to https://jetpack.wordpress.com/jetpack.authorize/1/?response_type=code&client_id=105537481&redirect_uri=http%3A%2F%2Fwww.echoesofchicago.org%2Fwp-admin%2Fadmin.php%3Fpage%3Djetpack%26action%3Dauthorize%26_wpnonce%3D9fb42c98b3&state=1&scope=administrator%3Ac36128ee6fa4c7f7f4b19af9bd832f6f&user_email=echoes%40gmail.com. I click the “update jetpack now” button, but that takes me to https://www.echoesofchicago.org/wp-admin/plugins.php?s=jetpack. Again, the menu shows up on the left, but the right side of the screen is blank.

https://www.echoesofchicago.org/wp-admin/admin.php?page=akismet-key-config (see 4 in screenshot file)

If I click any other menu items on the left side of the screen, the right side of the screen is blank.

I downloaded the newest version of WP to my computer hoping it would help but I don’t understand what to do next (if this is even a solution).

Thank you very much for your time and consideration!
