I have Aperture, latest version (I cannot check the version as Aperture will not open). When clicking on the Aperture icon, Aperture starts to open the library and then, after maybe 2 seconds, quits suddenly and shows the following message:
The last time you opened Aperture, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again?
When I click on Reopen, it shows the following:

There is a lot more text, staring with ' Queue 0' and so on.
It then gives me the option to open again, and if I click that, what I described above starts again.
I have downloaded Aperture from the app store. I cannot remember if I have a serial number.
I have tried opening Aperture while holding Option & Command. I have tried two of the three possibilities given, being Repair Permissions and Repair database. Does not help.
Tried shutting my Mac down and restart, does not help either.
I have a mid 2011 Mac with OS X 10.8.1. installed
My Library seems to be intact. I can at least find all the pictures in Finder, as far as I am aware
What should I do now?
Thans a lot for any help.
BTW: I am fairly new to Mac, so please be specific when answering or else I might screw up even more.
