I bought Studio 10 in 2005 and after buying countless add ons to improve editing options eventually upgraded to Studio 12 in 2008. Havent used it since. I bought the Mercalli anti-Shake add on, but the patch you need before that doesn't work. Support team is awful. Discussion threads go on for days. If you put it aside till you BP comes down, or just have to get on with something else in life, they close you out if they don't hear from you in 72 hours. There answer to everything in "go to this link", or "uninstall and reintall" I'm using Windows XP so maybe another OS is different. This program has ALOT of bugs
