Hi everyone, I've tried importing two different datasets using ArrayExpress and unfortunately I'm getting the same error: unable to find an inherited method for function "experimentData", for signature "try-error". Could you please advice what might be causing the problem? The R output is pasted below. Many thanks!

You really should update your R, but this is confirmed with current R 2.14 -- I don't know what is happening, there are many possible causes, and I will investigate a little, but others closer to this package should have a look.
