i am converting xenforo to ips. i converted attachments but it crashes part way through. can only get to 8866 of 9697 

clicking continue conversion just crashes again any ideas?

Do you see any errors in the error log?
If not, please submit a ticket so that we can take a look at this 

Do you mean error logs in the admin panel? If so there is nothing in there. 

I mean the  "System Log"  in the ACP or is anything in your php error log?

I found this

Hm, the error isn't related to the conversion process, it just means that IPS4 couldn't connect to your db because of the missing credentials ( ''@'localhost ) which isn't really related to the conversion process.
Please submit a ticket;)

Ah yeah that must have been when I entered the wrong password initially
