Help all ye Triplanar Gurus

I received my Triplanar VII U2 from Singapore over the weekend and I may have screwed up big time while mounting the arm.Basically, the screw that adjusts the height of the cueing platform broke in the hole with the screw head coming off,with the result that if I use the cueing platform to lower the arm on the record it seems to descend from Mt. Everest. Manually lowering the Lyra Skala on the record is not good for my health.
Have sent a mail to Triplanar and also the Dealer(Audio Note, Singapore).
I doubt if any A'goners have experienced a similar situation but there is no harm in asking.You have to be particularly cretin like to have achieved what I have done.
Am also unable to align the cart using the Best tractor supplied by my friend Yip in Hong Kong coz the mounting holes on the wooden armband are a bit askew. This can and will be resolved.
Will appreciate any help/ advise to lift my deep depression.
Many thanks
