profilux 3 help please..

[redseamax]

dear friends;
I have several questions.If you help me I would be grateful.
I have bought Profilux 3 starter pack a short time ago.also profilux touch.inside the package there is only one PAB cable and I use it to plug Powerbar-6D-PAB.. there is two PAB sockets on profilux 3 and I used one of them..now I think I need one more PAB cable to plug profilux touch display..so I ll use two PAB sockets on profilux..all of the L and S sockets are empty.. now I have tunze wavebox and vortech MP40 on my tank..also want to buy GHL PropellerBreeze5 PL-0718 and I think need to buy GHL PropellerControl-2.1 PL-0265.. so I want to ask what I need to plug and control all of them on profilux 3 1-10 volt sockets..I have already bought ;

GHL PAB-Cable-2m PL-0683 for profilux touch
GHL ProfiLuxTunze1 connection cable - Tunze L1 (L3) for wavebox
GHL VorTech Controller PL-0757 for MP40

did I do it right?
and what do I have to buy for propeller control 2.1 ? is it work on S or L ports? if it is which cable do I need?

also I have profilux controller ver 5.1.2.5 .it says "firmware 5.00 to 5.12" when I click to update to firmware to file that I download "ProfiLux3_V512_GER_ENG.mhx" it says on the last of the install "communications error!error code:41"and then "download cant be started-possibly a download is not allowed via the current interface!" and communication down.I ve connect to profilux via Lan cable..what am I doing wrong?

regards..
