Our main update server is down, and we have no idea how long it can last.
Coollector should switch to a rescue server, but we have discovered that v2.38 has a bug that prevents this to work.
That's why we have just released v2.39, which fixes this bug.
Since update is down, you'll have to download v2.39 from our homepage:

We apologize for the inconvenience
