Autotune prevents PT startup

[smilez03]

Hi,
I am considering purchasig Antares AutoTune plugin but want to try it out first. I downloaded the latest RTAS Windows plugin from the Antares site and installation is fine, plug-ins are in the proper folder, etc. PT wont launch now. It gets stuck on the plug-in while loading. It doesnt give a "not responding" message.
My PC isn't that slow. WinXP, MBox, PT 6.4

Any ideas? In the folder the plug ins are in i noticed the auto tune files are significantly larger than all of the other plug-in files... could this be why?

THANKS!

PT takes while to open for me as it hangs for about 30 seconds on my Waves plugs before continuing. How long have you left it so far?

Are you sure this isn't related to the other problem you posted?

Sounds like your system is a little unstable overall. Have you considered a complete re-install?
