3 Things Messing Up–Modern Blogger Pro Theme

Ok, so I have the Modern Blogger Pro theme installed. All things were great until all of a sudden one day I noticed three things wrong:

1) The font is messing up. I have the Open Sans Condensed Light font for the post titles and headers, but one day they just stopped. I'm actually wondering if it's a browser thing because now other website will have the Open Sans Condensed Light font all over the place. NO idea how to fix this nor make logic of how it happened...

2) With the WordPress 4.0 update, I can't edit or type in new posts. NO idea what to do there either... (I downgraded to get posts up, but would rather not have to do that).

3) Also with the WordPress 4.0 update, I can't access lost password. I apparently did a too complicated password last time because I can't remember it. So I clicked on the forgot password link and followed prompts. An email arrives in my inbox as expected, but when I click on the link provided to change the password, it says it's and invalid link. :-/ (Thankfully my browser remembers my password).

Things I have tried:

Deactivating ALL of my plugins (multiple times, and in different ways--like all at once, one at a time, all at once while the WP default theme was up....nothing changed these issues).
Switching to the WP default font (but nothing changed).

I'm not the most technical minded, so use little words please.

If anybody can help with one or all of my issues, that'd be great! Thank you kindly!
