@Scott T. It seems that there are in fact two accounts - with the same email and password login information. I was able to access my original one with my notes on Evernote web by viewing account information via a link on my windows native Evernote app.
Do you know how it was possible for me to accidentally create a new account? It seems like the system should be set up so that each email can only be tied to one account, ie it's impossible to create a new account with an email that already has one linked to it. In any case, my experience suggests that Evernote web defaults to the newer account without my notes, and I want to be able to access my notes online without needing my desktop app (or if my current PC crashes, I have no way of accessing my original account!). Is there anyway to select which one to login to?
It also seems like I cannot contact customer support since I only have a basic plan. Seeing as I have no need for the features of a premium account (I only have 2 devices and only use evernote for text, no images or multimedia), I don't want to pay for the features that I am not using. If I need to upgrade to recover my data I will, but I shouldn't have to pay to recover my own data.
Thank you very much for the help!
