Can't play with Maveric (?)

[Silverthorn]

can it be that maveric can't be played when there are other downloadable char or sth...

That is definitely not causing it. Just for fun, I threw together a little mod to play with my friends at school, in it there is maverick (and lots of other downloaded chars). Haven't experienced any loading problems at all so far. And they're all downloaded from LFE.

A little question that I have is this: did you try to manually install him? As in: insert the dats/bitmaps into the (correct) folders.
