<p>do u guys have difficulties submit and move to step payment? after iclick on submit the system said that "Unable to process due to an unknown error" the deadline was over and im so worried</p>
<p>Sorry if this is a late response, but I kept having the same problem yesterday when I filled out the supplement from the Common App website. I had to go to the Tufts site itself and fill out the supplement from there.</p>
<p>No! I'm having that problem right now as well! I've used all four of my parents credit cards and I'm submitting from the Tufts website. I have no idea what the problem is. Right now it's busy telling me that all of their card numbers are invalid...and I've filled out the form four times. GAH!</p>
<p>EDIT: It just worked...on the seventh try :P</p>
<p>IT WON'T EVEN LET ME sumbit the app... tufts website u say? is that legit, even if u use the common app?</p>
<p>Yeah, it was pretty frustrating because I filled out the supplement at least 5 times and each time it would give me some kind of error. I submitted the Common App, and used the supplement from the website and it went through.</p>
<p>Lol, I almost had a heart attack, seeing as I really really want to go to Tufts. </p>
<p>Mzjennnn is right: just use the version from the Tufts website. Oy vey! </p>
<p>Happy New Year!</p>
