I am perplexed how and what is happening?
I am just guessing here now and my time is limited
so....
Best Guess is a config file has got into a weird state.
I suggest you do either or both of the following.
1) Setup MaLa again from scratch in a separate folder and see if the problem follows?
2) Zip up and send me (or a link to download) the contents of you MaLa folder that is giving you issues
Thanks
