I could not load the externals from the "extra" directory, so I wrote the name of the directory in 'path...' preferences. I must have written something wrong (a "\" instead of "/" maybe?) because now nothing has changed and I can't even access the 'path...' preference menu.
What makes it stranger is that I can't access the 'path...' preference menu even after reinstalling pd.
This has happened both in WinXP and Linux (ubuntu).
Is this all very strange or am I plain silly?
