After creating a new module to host some custom web services (I got as far as deploying to IIS, and testing the service and WSDL URLs, which produced the correct response), I exited out of the dev apps (Eclipse, Visual Studio, etc.).
When I tried to resume work on the project later, started Eclipse, and received the following error:
"Unknown Feature" At dbwizapi.MsSQLAPI._GetPrgCtx line 25
Console shows: "ERROR MRUOpen: C:\OPENTEXT\module\cwstools_1_0_0\ospace\cwstools.oll failed (32)."
cwstools is the module I created earlier
I also noticed (and I am presuming it is related) that the Module Explorer now only shows a single module ); I believe that I should be seeing all the modules here (or at least that's what it looked like before I re-opened Eclipse to continue working):
