i want to run two instances of gruss, each with it's own excel sheet. Can I use two seperate profiles so each profile points to a different spreadsheet?
Yes. Make sure the spreadsheets are closed initially. Open each instance of Betting Assistant, select "Log current prices" then click the browse button to select the spreadsheet.
Sorry, I didn't realise you were using the Excel quick link option. You need to upgrade to the Beta version which stores the Excel quick link data separately for each profile. See http://gruss-software.co.uk/forum/viewforum.php?f=9 for download.
