Gmail Help

So today, I opened a gmail message that had a code for an omega ruby and alpha sapphire demo in it. I saved it for later. When I just opened it back up, guess what? The email had corrupted, putting a strange error thing in place of my code. Anyone know how to fix this? Also, if this is in the wrong section, please move it (staff).
This is what it looks like:

If google screwed this up, I will hate them SO BAD!

 

Send an email with proof saying it corrupted?

Edit: At the to right, it says you can view it online. Click that too.

 

Nevermind, I tried it this morning on my phone and clicked the link (link didn't work on computer) and it worked.
