I have no idea. All I know is that I hope its fixed in the next version. So far, I have tried uninstalling AC and erasing all directories related. AC, AC Prerequisites, & SAP Crystal Reports. Also ran CCleaner to scan registry, removed many entries for AC and Crystal Reports as the apps are not there any longer. Reinstalled the Client and I now have use of the field that it wouldn't let me do the enter/return. I still do not have the ability to print RXs and receive the same error as above. Any Ideas?
