Do not forbid speaking in tongues (1 Corinthians 14:39)

"So, my brothers, earnestly desire to prophesy, and do not forbid speaking in tongues." - 1 Corinthians 14:39

As a person who accepts a modern view on tongues (albeit limited to being done in private or when there is interpretation - what I see as the Biblical model) I have no trouble making sense of this verse.

If however, you have a problem with tongues or prophesy, what do you do with this verse?
