Cuprate i think would mean there is oxygen combined with the copper. like for chlorate(1) which is ClO-. the -ate suffix generally means an oxide.

It's possible that they are saying that by writing copper(II) you are implying cuprate, and therefore don't need to say it. For example, nowadays we don't say sulphite and sulphate, we say sulphate(II) and sulphate(III)... I think.

best guess right now is : tetrachlorocuprate(II) but better is to check in a General Chemistry textbook or an Inorganic Chemistry textbook.

You must be naming according to IUPAC nomenclature rules. IUPAC doesn't recognize 'cuprate'; it is either copper(I) or copper(II). 'Cuprate' is often used in the literature but it isn't strictly correct according to IUPAC. It is particularly offensive (to chemical geeks like me) that the -ate suffix is used to apply to a positively charged metal when everyone knows that even under the old nomenclature system that -ate was the nomenclature of heteropoly anions!
