I can' t begin to tell you how important it is to take it to a pro-shop to make sure everything is okay. From the way you talk, you didn' t have a bow press and frankly, I don' t know how you' d do that without one. Even a portable string press. Anyway, so much is important to good shooting. Improper placing of the string on the cam can cause problems with cam rollover, nock point travel, draw weight, and letoff, etc. You need to let a pro shop check it out, then adjust it to fit you if possible.
