Halion Sonic 2 not working in Garageband 10


im interested in buying this vst as i like the idea of a pool of bread and butter sounds and nice synth engines, so i downloaded the new trial of 30 days and installed it, all perfect.

The standalone works great, the vst works great but i the audio unit in garageband is not opening at all. It says that it needs to be updated and that i need to contact the developer.

As im moving to Logic pro X soon i fear that it’ll have the same behavior so id rather get it working in garageband so i can relax when i get logic pro x

Hope somebody can help.

my mac is a MBP retina mid 2014.
