Outlook Plugin Disappears Frequently

Hello,

I have gone through the past couple of years noticing my Outlook Plugin for Zoho disappears from my toolbar.  I have looked in the Outlook Options>Add-Ins section to find it in the "Inactive Application Add-ins" section.  I have reactivated the Zoho Plugin, and it stays for a while.  Then it randomly disappears again.  I have tried the alternative method far too many times of uninstalling and reinstalling the plugin.  I am running Windows 7 Ultimate 64-bit with Outlook 2010 version 14.0.7128.5000 (32-bit), and I have installed the 32-bit Zoho plugin.  Several other people in my office have been going through the same issues.
