Cream Cheese can be frozen and when frozen the cream cheese will last for up to a year.
However cream cheese does not freeze all that good and when you do freeze cream cheese it's texture and taste can change.
That doesn't mean that the cream cheese has gone bad but it just won't be as enjoyable as fresh cream cheese would be.
Frozen Cream Cheese is best used in baked goods where the texture and change in taste won't be noticed.
Cream Cheese can safely be left out at room temperature for up to 2 hours.

If the cream cheese has any mold on it, has a bad smell to it, or has become really crumbly or hard then it's bad and should be thrown out.
