I wouldn't worry about it too much.
Last year, the PSI website screwed me over and froze on me the entire time so I had to reschedule. I took the first portion a total of 4 times before they finally said to reschedule. Called and rescheduled and worked fine the second time. Honestly I think I did worse last year than I did the year before that but I got well qualified without any atsaprep practice, not sure what i got the first year. I'll probably do some prep before my test next week just to try to get some extra points. Which reminds me, the bright side for you is that you get to prep some more and now you know what's on the test!
Seems like they really screwed over salt lake city this year. The closest testing center is in Boise, Idaho. boo.
edit: kinda odd that they said they would contact you to reschedule. I remember when I called, they told me they would just send me another email to schedule another time for the test.
