Ok, trying to install prestashop

[guru]

Got to step three and now I'm getting this error

Error while inserting data into the database:
'CREATE TABLE `ps_tax_lang` ( `id_tax` int(10) unsigned NOT NULL, `id_lang` int(10) unsigned NOT N'
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near \'N\' at line 3(Error: : 1064)

But, when I do a repair and try to go onto to step four, it tells me that a prestashop database already exists, either delete it or change the prefix. However, I believe if I change the prefix, I will get the same error above and still be stuck on step 3. Is there any way to jump to step four and finish the install?

Thanks for any help.

Nevermind. I figured it out. Evidently some files got corrupted during the upload. Re uploaded and completed install.
