How to restore/convert from Quantum?

SUGGESTED

Hello. We recently purchased Sage 50 Premier for our small business.  Our accountant has our information using Sage Quantum.  I am attempting to restore from the accountant's backup to our software, however I get a message that I cannot restore from Quantum using Premier. Does anyone know of any way to import the information, so I do not have to manually enter all of the transactions and information? I am new to Sage software. Any information is greatly appreciated.
