Is Electrum connected? Check right bottom, is there a green dot? Maybe Electrum is not 100% up to date?
If there is not a Green dot check the connection. Go to Tools-->Network and check if Auto-connect is checked.
Yes, green dot and auto-connect already checked.
Then it wouldn't make a lot of sense , if RustyNomad suggestion above don't work you either .
You can try to Unistall Electrum (deleting electrum's AppData folder as-well) and Install it once again , if that don 't work , try to use it on another PC (restore it on another PC using the seed you had as a backup when you first made the wallet) .
So as long as I have my seed I won't lose anything, correct? I've never done that so it makes me nervous.
Not sure what happened just now, got a double post in one post.
Was saying, if Electrum is up to date and the address is in your wallet then maybe all that will work is what OmegaStarScream suggests above.
And yes, all you need is your wallet's seed. With that you can restore your wallet at anytime. You do not need anything else, just those seed words. So always keep a copy written down somewhere and keep it in a very safe place. Anybody who gets hold of that will also be able to restore your wallet and have full access to it.
I edited the post to have them both since I don't know if I can respond before 5 minutes yet.
Thank you so much guys, restoring worked and I didn't have to reinstall the app, just deleted the data as per this document:

Again, thank you both so much!
