it seems i will need to open a special support line for all u guys. just to avoid keeping u wait. sorry for the delay. if u wish, contact me on msg (there info on my profile) this weekend so we can have it done without wait.
ok, let me see what u have done till now.
1. yes, u need the multi-proc patch, plz install it, according to the instructions from the link.
2. 1.7a patch is not needed, but will not do much harm anyway, just let it update a few times before entering mp. anyway, the rule is that if 1.7 updates without error activating mp button on launcher, u can skip 1.7a patch with no fear.
3. there's a problem in ur installation, because u r using different paths; plz, uninstall and delete everything again, and install again (using ur paths if u wish) just b sure to install freelancer 1st and flmm 2nd. that way flmm will acknowledge ur fl folder correctly, which it doesn't do if u install it before fl (guide doesn't comprehend advanced users and installation on differents paths, unfortunately, but it was written for typical users in the 1st place),
4. before u install cf mod as the last one in the process, plz check fl directory setting in flmm (options menu), and turn off read-only option too. then proceed and i think ur troubles r gone away. let it update, start, set the options in cf fl, exit, start again, let it update, enter mp, enjoy life. 
btw, because u seem like a nice guy, i would like to stay in touch with u regardless ur problems r finito. msg is my prefered contact, just add me if u use it. and c u online. :]
