ok down to last program that wont work with XP even though out side of box and calls to tech supp say its xp compatible

i get following error message..

mpl loader.......
the dll "mplapx.dll" can not be loaded OS reports the specific module could not be found............


attempts to fix
1. under xp changed compatiblity (fake it into thinking its win 95/win98/win200/NT ) each one was a try

2. un/reinstalled movie factory

3. downloaded trial version (same error)

4. re installed XP

after hours on phone with microsoft we found this dll to be in the ulead program causing the problem (ie no mpegs would play in any media player ....winxp/mplayer2/nero's/mgi videowave....all had SAME error

un installed movie factory and everthing else worked great

any ideas?

thanks
