Which Crystal Reports version do I need to buy?

I need to edit and create reports for "Conference Programmer" software and need to know which version of Crystal reports to buy. I started a chat with somebody on the main SAP website and they couldn't help, called the number he gave me but they couldn't help, they referred me to another number which had 20 menu options which ended up at the sales area. They couldn't help and told me to email the on line store. The chat guy then said to join here and ask.

Seriously, if I didn't need this software I would have quit by now.

"Conference Programmer" folks said to get at least version 11. SAP doesn't list them that way. Will the standard "SAP Crystal Reports" meet my needs?

Thanks!
