error loading a microsteam database

[guykatz]

hi all;
I am playing around with several things microstream related.
I already have a decent microstream storage with data.
somehow, I got to a point where microstream cannot load the DB and produces the error below,
any ideas whats going on here?, I didnt do anything out of hte ordinary...:
