I completely agree with the comments Kuler has made. I thought I was losing my mind when I saw all those $ symbols and the almost the throw away remark by saying "all that has to be done is...".
There was no mention in the sales information that these changes had to be done manually for it to work as stated.
I myself am beginning to look foolish as my client is wondering what is going on with the website. It is all well and good stating that as yet no timescale has been set for a global fix. The currency issues should have been made clear at the start and that PowerStore would not work with other currencies unless manual code changes are made by the purchaser (which of course defeats the object of purchasing this software).
