Looks like an issue with the version of MySQL they are running not liking the length of some of the fields in that table. I'll need to change the base code so this doesn't happen. What you can do is change two lines. In the createtable.php script look for these 2 lines:
BBCODE_MATCH_REGEX varchar(256) default NULL,
BBCODE_MARKUP_RESULT varchar(2048) default NULL,
change those, to this:
BBCODE_MATCH_REGEX text,
BBCODE_MARKUP_RESULT text,
