I have noticed when looking at who is online, those that stop the process are usually at this point:

I have not seen this before, but what does this mean? I'm not sure where to look to resolve this issue. Thank you in advance.
Are there any LOGFILES generated as a result? You may need to enable error logging within your payment module.
There is a file related to ajax and credit card processing which was introduced in ZC1.5.4
Have you asked your credit card processor who provided the files to you if the file is applicable to ZC1.5.4?
