SQL Error with RBCalc - Any Suggestions?

[PatInTheHat]

I know I probably shouldn't be using RBCalc any more but i've never had any problems with it. I just recently converted my database to SQL and now when I try to use RBCalc it gives me the following error:

Error - 1 perofrming SQLDriverConnect
SQLState = IM002
SQL message = [microsoft] [ODBC Driver Manager] Data source name not found and no default driver specified.

I can find no reason for this happening. The program works fine with my Access databases.

Anyone know a fix? Or is there another program I can use to determine my rakeback?
