Neither. What'll end up happening is I'll play, get XP then close the browser. Come back later, load up and the XP will be gone. Even the online saving isn't working. Supposedly you can save through armorgames but whenever I click that button it just freezes.
I've never even heard of that. Well on my account. Then I play and leave and come back it saves on its own. The only way I could think this is happening is because there's something wrong with your cache. You should ask cormyn about it. He's an Administrator on the site. Here's his profile. Just leave a comment on his page.
Nevermind, I figured it out. I think it has something to do with signing in prior to it reading the the files saved on the comp. I'm not computer genius but that's my best guess.
