I have Outlook BCM 2010 on new PC (Windows 8.1) with Office 365 64 bit. Had message that Outlook detected an addin problem with Atheros Outlook Addin 2010 and now I cannot open BCM. It is listed under my Personal Contacts. How do I get my BCM back? I'm not sure what Atheros Outlook add in 2010 is or if I need it. If I recall I chose 365 64 bit because I was trying upgrade from Office/Outlook with BCM 2007 and otherwise would not install correct SQL server. Thanks.
