Hi Davy,
Thanks for posting! It looks NCrunch is having difficulty in constructing a workspace for one of your projects and is unable to report this error due to a defect.
I've noted the defect down for a fix in a future revision. Meanwhile, let's see if we can find out why the workspace is failing to build.
Try changing the 'Workspace Base Path' setting in your global NCrunch configuration to point to a path that's close to the root for your disk - for example, C:\NCrunch
Workspaces can often fail to build if the solution you're working in contains especially long file paths, or if the workspace base path is set to an invalid value/location.
If this doesn't solve the problem, please submit a bug report after the error has occurred and I'll try to track down what has caused the issue.
Thanks!
Remco
