"I hope you're not disappointed" should be accepted because this sentence can be meant in the future tense.

希望 (xi wang) = to hope; to expect. 失望 (shi wang) = to be disappointed.

XīWàng ShīWàng

"I hope you don't lose hope" seems like a reasonable answer to me.

June 2018: now that you build an answer from a word bank, it makes me happy that my leftover (unused) words were "chocolate pork" How could I be disappointed with that?

I think "I wish" should be accepted as well, it has this meaning, too.
