I tried the Scala plugin 0.3.55 in IDEA 90.94. Directly after the start the green info box tells me that the Scala facet could not be loaded. And that's the only message I get (no exceptions). The Scala plugin is just deactivated in the plugins list.
Anyone having the same problems?
At the moment I switched back to version 0.3.52, since this version works.
