dissappearing logic authorization

[macStuff]

hey guys
so i pluggd in my xskey last night
blue emagic usb key version
fully expecting that it would authorize my logic 5.5 that i was messing around with
and it says it has no logic authorization on it
and now its only showing a registration for ES1 synth for both mac + pc versions
im perplexed because i bought this blue key off ebay supposedly as being a full logic version 6 that was upgraded from 5
is there any explanation for why my key is showing no logic authorization ??
it seems to me that my auth has vanished
maybe it only works with mac on logic 6? because it upgraded from 5 to 6?
i swear i used it on pc for 5.5 before tho. so its very strange
the white apple xskey i haev works on pc to authorize basically everything

just found this thread;; apparently this was a bug in early version of winxp? requiered a "fix" for it to see the auth?
wierd

stuck it back in the g5 and it works there to authorize logic 6.
is the auth not downward compatible? ie: wont auth 5? only 6?
on the pc it only showed up as having ES1 authorized - strange
