I was attempting to purchase AlteredCart's 'one page checkout' and this warning message appeared (pictured below):

I didn't change, nor did I enter, any registration information.
I cleared my cache, closed my browser (Firefox 2.0.0.14) and tried again, but the same warning message appeared. I can click on the 'reload cart totals' and that seems to fix the problem, but I'm reluctant to purchase the program if it is buggy.
Is there a fix for what I perceive as a problem? Or is this normal?
