@lat9 Got you test message, thank you. I had to reverse to the older version since the new version does not operate. Or you would not be able to send a test message.

I think I replaced all files of the older version. I read both READ ME files (for the original version and the version I am installing) and I saw that the new version should overwrite the older files as they have the same names.

Here is the debug file information.

Code:
