Email Issues

I had my email client crash this week, and it will no longer open:( I am able to get new mail (although I wasn't for several hours), but I cannot access my address book. If you think you should have heard from me and haven't...I may not have your contact info anymore...yes, this is a nightmare at the busiest time of the year. Please send me a quick email if this might be you, so that I will have your contact info again. Thank you for your patience:)
