Is there any explanation why updating ProTools 9.01 to 9.05 would cause my Mac to lose its authorization? Especially when the iLok still works? Rather than buying support on 9.05, I upgraded to ProTools 10.01, which then for some reason no longer works with any of my plugins. I now have all my previous work stranded in a version that won't run on my computer, and a new version on my computer which cannot run my plugin collection. Call me disappointed. The cost to repurchase these plugins is more than I'm able to budget for; but ProTools 11 will likely be 64bit, requiring me to re-purchase them once again. This is depressing.
