SAGE300 & RAZOR's EDGE cant both run w/ latest version of Crystal Reports

We are in the process of upgrading our SAGE300 to the latest version. We currently have razors edge and the latest version of crystals reports installed but crystals report isn't allowing the SAGE300 upgrade to run properly. Is there a way to doewngrade to an older version of crystals reports that will allow both Razors edge and Sage 300 to run property without any issues? If so, which version of crystals reports should we downgrade to?
