Try downloading the update from Spectrasonics' site. Logic 7 had a new method for scanning AU plugins which caused some to not validate properly, Atmosphere being one of them. If you download the latest update, you shouldn't have a problem.
thanks FV ... I went to Spectrasonics web site ... looked for an update on Atmospheres and the only update I could see was for RMX. I was going around in circles trying to see if Atmospheres had an update and couldn't find it. I hit all the areas (I think I did .. maybe my old eyes need stronger specs) and got a little frustrated. I'll look again.
ok ... call me silly .. the reason I wasn't seeing Atmospheres update, was because the system was defaulting my serial number for Stylus ... when I put in my Atmospheres number ... it sent me there. Hmmm ... I must be getting senile.
Thanks for the suggestion FV .. I've downloaded the update and I'll try that.
