on importing old credit card charges into a newly linked to quicken bank account: can i do this?

I just started using quicken and linked a bank account with a credit card account. I have saved .qfx files for the last year I was hoping to be able to import into quicken for the credit card from the bank. when i tried to do this I got the error
"The financial instit had downloaded data for an account that does not exist in your quicken data file ol-362-a"
when looked up on the web was told this was because accout information was out of sync with the server which makes sense since these entries came from me.
Can I import the entries or should I just go from the present time forward and forget about entering past expenses to try to see spending patterns?
