Cubase 6 (64bit) - no mp3 option

Good day! So I needed to run a plugin that runs on 64 bit only, so in my Cubase’s properties I un-checked the “run in 32bit” and I noticed that it wouldn’t let me export in mp3 anymore. I need that, so I can give small samples to clients or bandmates. Can I somehow fix this? Thank you in advance!
