its the right version I need, which is the ME version, and I highly doubt that it's something of incompatibility, because both the OS and the software are quite modern, and Adobe have studied how to adapt their new CS5 programmes with Windows 7 and Vista, if not even they wrote their CS5 programmes on the basis of modern OSs like Windows 7.
- I noticed that this error started to happen after I installed DisKeeper 2010 as a trial, and then I just missed around with the programme (Diskeeper) and deleted something it indicated me to (gave me the choice to whether delete or not) but later, I just found that I should stick with O&O Defrag, that's why I uninstalled Diskeeper...
and then found my self stuck with not being able to launch ID CS5 ME after quitting it, till I check with Task Manager to manually quit it, that was the only way that I will be able to execute ID CS5 ME again.
but on the same hand... this doesn't always happen, it most likely happens after the first use of ID when I log on to Windows, but later, when I quit it in Task manager, and then run it again, I just see that I don't need to go with all this boring procedure again with Task Manager and what not, so I can run it again after quitting it even without checking with Task Manager.
I hope I have explained well.
