The fix is to download this file:
http://members.dinkum.net.au/plai33/ECP2Beta3.zip. Now, copy the ECP2Assembly.dll file from the ECP2Assembly\bin folder in the zip file and place it in your mediaportal folder, overwriting the existing one. Make sure MP is not running when you do this.
I should have told you I was running 0.1.0.9 when I posted that, after reading your reply I quickly upgraded to 0.1.0.10 to try it.
But still nothing... I also tried it on 0.1.0.9 without any luck.
I noticed in ECP2Assembly.dll.config has is a key "MPDirectory" which has no value, could this be a problem?? could there be another file?
