Hi,
From the top of my head.
It does'nt look like there is a Arturia download going on.
If you are on windows, then it might help to check the network activity in the task manager.
If you have any download programs running automaticly, then that might be the issue. based on what you write that might be the case.
If you have tried to download AL before, then you can check the download path to see if there is a AL download file on that path, and then delete it, if there is.
