Download ArtMoney here , select 'download from this site', the usa one was corrupt and wouldn't work for me.
Backup your MVP 2005 folder in 'My Documents' (you can just right click, send to compressed folder if you want)
-after you install it, run MVP, goto set ticket prices and take note of how much money you have. ALT Tab out to minimize MVP
-in ArtMoney, choose MVP 2005 from the 'select process' dropdown menu
-click 'search' , then in the search drop down, choose 'range of values'
-in the values box, enter in an amount 1 less and 1 more than the number of dollars you have
-in the 'Type' dropdown menu, select 'Float' , then click ok.
ArtMoney will search for that value, you will most likely get a few results but I found that the correct one was 4bytes, it was the only one that would allow me enter a number that large.. just change the value.
GO back into MVP, back out of the screen you were in , then go back to set prices... your dollar amount should change to whatever value you put in.
I entered 999999999 and it gave my 1 Billion even.
Its not hard, I figured it out in less than 5 minutes..
