Immediate error when running instaup2date.py

Hi everyone! Total instaDMG newbie here and have been doing what I can to figure this tool out using websites and googling. I was able to successfully get instaDMG to give me a plain vanilla 10.6.8 image which is wonderful. I've been successfully using it to deploy hardware at work with updated 10.6.8. I now want to start customizing w/ standard settings, users, and various applications. When running "sudo ./instaUp2Date.py -p snowleopard" it spits out the following: Parsing the catalog files for snowleopard Traceback (most recent call last): File "./instaUp2Date.py", line 716, in main() File "./instaUp2Date.py", line 662, in main thisController.parseCatalogFile() File "./instaUp2Date.py", line 286, in parseCatalogFile self.parseCatalogFile( self.getCatalogFullPath(includeLineMatch.group("location"), self.catalogFolders) ) File "./instaUp2Date.py", line 286, in parseCatalogFile self.parseCatalogFile( self.getCatalogFullPath(includeLineMatch.group("location"), self.catalogFolders) ) File "./instaUp2Date.py", line 319, in parseCatalogFile raise Exception('Error in config file: %s line number: %i\n%s' % (fileLocation, lineNumber, line)) # TODO: improve error handling Exception: Error in config file: /Users/dbong/Desktop/instadmg/addons/instaup2date/CatalogFiles/common.catalog line number: 2 ? What am I doing wrong here? Thanks!
