I am so dissapointed

[dossisen]

I just bought the Longitudinal stop LA for my cms table.
The  precision in this piece is some kind of joke.I never in my wildest imagination thought they could sell this kind of crap.
The engineer of this "Masterpiece" must have been a child.
You actually need 2-3 hands to move it sideways and when you then tighten the knobs it will often be pointing towards the sawblade.This is a really dangerous using it and in my opinion it should be of the market right away.

Please tell me I'm doing something wrong because otherwise I  have no other option then selling the hole tableset and lose a lot of money.

I have this fence since a few years and it is in my opinion a very precise addition to the CMS table.
I go as follows:
I turn the knob until the scale is at 0 (zero). Then I slide the fence over the fixed ruler along the table to about the desired distance.
I fasten the small handle at the underside. Then I fasten the big knob from the V-groove clamp. Then I clamp the back clamp with the small handle above the big knob.
Now the fence should be parallel to the saw blade. I measure the distance between the fence and a tooth that was bended to the right (when you alternating teeth).
If you need a correction, you loosen the back clamp and the V-groove clamp. Then turn the knob of the scale until you feel a little resistance, then turn the needed distance and clamp both knobs again, first the V-groove. Check again and correct if needed.
My only point of critic is the play in the thread of the scale and the experience you need to gather to know if you have to turn clockwise or counterclockwise to correct.
But in all cases you need to clamp the V-groove first and then the back clamp. Otherwise you may end up with a non-parallel fence.
If you end up with a non-parallel fence, you should contact your dealer.

I have the Ripping-cut fence LA on my CS50 and although there are three knobs, I can happily slide the fence, adjust it with the micro-adjuster, and then tighten it down with just one hand. 

...and when you then tighten the knobs it will often be pointing towards the sawblade...

My fence locks down parallel with the blade and I have no complaints at all.

Please tell me I'm doing something wrong...

Certainly.  I think you must be doing something wrong!

I suggest that you investigate further, and if you still aren't happy with it, see your Festool dealer.

because otherwise I  have no other option then selling the hole tableset and lose a lot of money.

You say you have just bought the LA fence - what were you using before on your CMS? Some people don't buy the rip fence at all, and just use the Angle Stop WA. It can be mounted on the front or side V grooves of the CMS, and although it doesn't have any micro-adjustment and only has one point of lockdown, I find that it is surprisingly solid.
