Hi, A friend of mine give to me UX2 as a present this week. He used it twice before in the last year. When I install podfarm, (I have the original CD) it says that the license is Ok but is not authorised for my computer. I uninstall everything and try to install again and it says to me that line 6 monkey is running, therefore I cannot install podfarm. I uninstall everything one more time but it doesn't work. Is my first time using UX2 and I'm not an expert in this kind of things. What I'm doing wrong or what's the solution to my problem? Thanks a lot.
