Universal Email is not functioning

I have Universal Email 401 installed DWCS6.
I created form page years ago and it is still working fine.
Now I created another form and it is not working.
It looks like working and it go to pages set on the UE panel after clicking submit button, but it is nos sending the mail as I don't receive it.
The email is set for pear mail using smtp.
The new form I created is under the same server where the old form is working fine.
I compared the settings of the UE panel and they are exactly the same.
I also found the error log on the server as follows:

[17-Jul-2013 11:40:09] PHP Warning: require(contactform.php) [<a href='plugins/function.require'>function.require</a>]: failed to open stream: No such file or directory in /home4/pagodad1/public_html/webassist/email/mailformatting_php.php on line 142

I checked the 142 line and it was

require(basename($fileName));

I don't know what that means, but I checked the same files on the working one and it has the same 142 line.

I deleted the confg folder of the DW and deleted the extension and reinstalled, but still have the same issue.
