Query: Save your money!!!!!!!

Unless you have a computer with 1995 windows or lower DO NOT BUY!!!!!!!!!!!! NOT COMPATIBLE!!!!!!!! It isn't worth one cent! With a lot of work I got the CD to work, but my computer kept closing down the program because it thought it was a virus. My computer which has Windows XP did not recognize many of the programs charachters so if your confused about Calculus it will only confuse you more. It's useless, I regret buying it. Save yourselves!!! And your money!!!!!!!!
