First of all, if you are using RC's and betas, expect to encounter difficulties
Second, the RC1 had a number of bugs in the sql scripts, where the table prefixes were not correct for certain tables.
The problem you are referring to is likely to be the same.
when you see something like :
#__blablabla
in the sql file know that the #__ is the part that will be replaced by your mambo setup table prefix. In the SQL statement that part should be quoted as follows :
`#__blablabla`
This should fix your problem
Take care, and get RC3
