Error in a product page after we installed Friendly pricing contribution

[nnesin]

Hello, yesterday we installed "Friendly pricing" contribution but something went wrong. On our product page we are getting this error

"1064 - 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 '' at line 1 select value from currencies WHERE currencies_id = ". Also, the product page is missing the right hand side navigation. If someone has an idea what should we do please, let us know. Thank you!

REmove the contribution and restore a databse back up immediately prior to the install.

Get it back to working again then try once more
