I'll give this one star for being good on the rare occasions it works. With Studio 10 I experienced many problems with the programme crashing. However when it worked it was good, and in an attempt to solve the problem I bought 11. I loaded it on to my laptop, and within minutes it crashed. I then reloaded it, but the same old problems. At which point I emailed the help desk, who replied with what appears to be a very standard reply telling me to try reloading it!! In the meantime I loaded it on to my PC. For one night it worked well, but on loading the project again the following night, it crashed, and now instantly crashes as soon as it reaches 100% open. If this was a problem on just one computer I might give it the benefit of the doubt, but not on two. It is also worrying to read the number of references to crashing problems in the trouble shooting in the manual, indicating that I'm not the first. To rub it in, my email reply to their "customer care" response has just been rejected despite my following their instructions to the letter. I'm now looking elsewhere.
