Created demo to test phpBB migration - having issues

I created a demo XenForo site in order to test the migration process and (hopefully) to give some users on my side the opportunity to evaluate before my company makes the switch. However, I'm having problems during the migration - and I don't know if that's a result of using the demo site or an issue with the migrator itself.

First issue is the migration process not finding my attachment or avatar directories. I confirmed that I can directly get to those locations with a browser, tried prepending with "../", and eventually just said "nevermind" and pointed it to my "styles" directory which it didn't complain about. After that, it starts giving me the following errors, which from another forum post suggests that the target filesystem is out of disk space? Can anyone help me understand if this is a limitation with the demo and if so - is there any way for me to examine a migrated database without buying the full license first?

here's the output from the migration tool:

Yes. The import tools are there and I figured, since I could create my own forums and what-not, that I could do an import as well and test not only the migration process, but the look/feel/capabilities of the board post-migration and use that time to work through any potential issues I might have. If I can't do a migration into the demo environment, is the only way to do an extended test to purchase a license and go through that process on my end and see what works and what doesn't?

If your database isn't too big then I can run an import on my server using my copy of XenForo. Then I can give you a URL and login so you can test it out. I would need a copy of your database.
Thanks for the offer. This is, however, a internal corporate forum - so I'm a little hesitant to send over the entire database. Are you an employee of XenForo?

I'm a volunteer. But I understand your concern.

The only other option is to buy a license so you can run the import yourself.

Yep, that's what I figured. Thanks!
You can trust Jake, Ryan. He's helped many people out who have given him access though i do understand your concern but i wouldn't hesitate in taking jake up on his generous offer if I were in the same boat.
Thanks for the +1 Shelley. I might very well do that. It's towards the end of the day here so I'll consider and move from there.

Another +1 for Jake.

He has literally helped 1000s of people, many of which via direct FTP, Admin and even shell access to their servers.

If there's one guy to trust, it's Jake Bunce :)
