Call to undefined method authorizenet_aim::tableCheckup()

[Appa306]

I am still in the process of setting up my site before going totally live, and am testing various functionality.

This morning, I tried to "edit" an order placed by one of my testing customers, and I got the following error from the debug-error handling function in 1.3.9h:
[14-Jul-2011 10:14:24] PHP Fatal error: Call to undefined method authorizenet_aim::tableCheckup() in /home/content/51/7938251/html/zencart/includes/modules/payment/authorizenet_aim.php on line 108

This section of the code is something to which I have not made modification, so, needless to say, I am puzzled.

If anyone can offer a suggestion as to what is needed to correct this error, I would be very grateful.

I did not put my URL in the post, thinking it would not be needed. Having no responses, I am adding my URL to the post, in hopes that someone will have an idea on what needs to happen.

I hope someone will have an idea.

Thanks

Please ignore this post. I have fixed the problem by reloading the original file, and reapplying the updates.

Sorry to take your time.
