Hello,

you are probably having the issue described here:

https://portal.smartertools.com/community/a93414/cant-reply-to-certain-messages-array-dimensions-error.aspx 

The fix would be to install the custom build 7508 that you should request in the other thread, or wait for this week new release.

Let me know do you have any latest build to over come the issue ?

Thanks

I'm going to mark this as "Resolved" as the array dimension issue has been fixed and will be in this week's release. (Custom Builds have proven to fix the issue as well as a couple of others people have experienced.)
