pls help me with the following problem: I had downloaded Parallels Desktop for Mac as a trial version it appeared to be working satisfactorily and I decided to buy the full version. This is where the problem starts. Whilst I was traveling, which is part of my job, it appeared difficult to buy it online and I ordered a cd-version through my office in The Netherlands. It took a considerable time and the trial expired. When I received the code from the version bought in Holland, it did not work with the installed version. I removed the program from the harddisk and installed the cd-version. However since then the program refuses to open and I am unable to use it or cannot even put the activation code in. When i read back, this is quite a story but the bottomline is simple: the re-installed version refuses to open. Please help me to resolve this problem so that I can use the program.
