No how do I contact Arno . Thanks John you've been a big help. I agree as well. It's really hard to know which tune to pick out. I tried the most recent tune first but it didn't work. I'm on vacation in Vegas right now. It's been a heck of a time for only being here fully one day . My wallet was taken and got it back today.
