I'm trying to move over to Snitz from UBB and I've tried applying the import.asp scripts that I found here but I haven't managed to get either of them to work. If anyone has already done this I could use some help.
I've made a lot of progress. I've managed to import a user base of just under 8000 with no problems. Like you I found that the script would stop but then I checked where it was falling over and discovered that it fell over under 2 conditions. Some of my user records were 0kb's and some were corrupted. Once I removed those files from the memberlist.cgi or replaced them with backups the script worked like a dream.
