Error during the table creation process

[N7legend]

Hi, I'm trying to install thirtybees 1.0.4 on my website, but when the installation hit 25% i've got this error: Ajax request failed for process installDefaultData=true with parsererror. SyntaxError: Unexpected token < in JSON at position 0

can someone help me ?

Unexpected token < in JSON at position 0

This means some Ajax callback delivers HTML instead of JSON. Usually an error page.

Last time this was seen it was solved by re-uploading all the distribution files, deleting the database and starting over. If this doesn't help, more information is needed. If you don't feel like entering Firefox' developer toolbox for looking up what that non-JSON is, I'd ask for web access, so I can attempt an install myself.
