Tested on your site with your account. Gives an error 500.

Have checked the module. All is running absolutely good on my computer. Have access to the previous Orders normally with the tracking numbers displayed.

The module is good, if not, other people would have noticed me that pb long time before.

Certainly you have a typo introduced by cutting and pasting.
See commas at at of lines.
Recheck or use 'debug error utility' from ZC modules to get the bad line.

PS: Im not online everyday to do support for customers and their shops. Its GPL.
