Error : Could not initialize class com.altera.systemconsole.internal.plugin.jtag.aji

Hi, I forgot to reply to this thread. The system is working again.

But, because there is a but, I can't explain why it wasn't working and why it works now. I have tried several times several way to have my download to success:

- I have closed eclipse and started it again => no use.

- switched off the computer and reboot => same here.

- re-install the USB driver => again it wasn't that.

- others stuff I can't remember.

And every time, the same error message appeared.

But once, and I don't know why, it worked, and since, I don't have any problem anymore. I should have done something to change the behavior but I don't know what it is.

To answer your question : yes, I have quartus 9.1sp2 and quartus 10.1sp1.05 installed.
