Password error when trying to upload a Memo to Google Docs

I used the memo app on my LG AS870 to inventory some equipment in storage at work. Then I went to upload the memo to my Google docs to transfer to my pc. When I try to upload it, it asks for my Google email address and password, which I know are correct, and every time I try to sign in, it says incorrect email address or password, please try again. I signed into Google on my PC to verify I have the correct password, and then even changed my password just to be sure, but still the same error. I'm already signed into Google + and Gmail on my phone, Google docs is the only app I'm having this problem with.

Welcome to Android Central!

Do you have multiple Gmail accounts on your phone?

My phone did have another Google account on it at one time. I had temporarily traded phones with my girl so I could fix her phone when she was having problems with it. But her account has since been removed, and when I go into "Accounts and Sync" and click on Google, my gmail address is the only one that is listed. (the original post was mine, but I wasn't signed in at the time, but it made me sign it to reply)
