hi again......just an update on my post above. I have updated and installed from 1.1.2 upwards to 1.4.1 which allowed me to install but I cannot see v1.4.1 in Logic, only 1.0 and when I load it as a standalone on my macbook pro, a box comes up asking me to put in my authorisation code but when I try, it doesn't let me put it in and will only run on demo. I have no idea how to resolve this. I have tried to authorise it on Logic's au prefs and spark vdm 1.0 is au'd but spark 1.4.1 is there which will not validate and just hangs up logic.
I would really appreciate some help as I have just bought Spark and would like to have this sorted.
Many thanks, Nick
