When I'm trying to create I get the following error after pressing next on the first screen:

[FormatException: Input string was not in a correct format.]
   System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) +295
   System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) +175

I played arround the hosting plan settings (from unlimited to a set amount) but it still won't go the next page.

Any idea what this problem could be?
