It's impossible to know what you're doing wrong if you don't post a .cap. My first guess would be that the image of your sprite is off. if the angel is 0 the sprite is facing to the right, so if you've painted it facing for example straight up it would be 90 degrees off.
If you want help, allways try to privide a .cap. like 2 of 3 posts here in the help section follows a strict pattern:
1: Help! ~random problem~
2: Post a .cap to get help.
3: Ok. ~.cap~
4:~solution~
5: Thanks!
