Tensioned element and loads

Hello. I am new to Abaqus and with a somehow unusual problem.

I have a horizontal cable modelled as wire, element type truss T3D2, no compression material, to which I applied pretension stress in the initial step.
The cable is connected to (almost vertical) beams at each of its endpoints via join-type connectors. Due to design requirements, I need to apply lateral (horizontal) forces at these shared endpoints, but the job keeps on failing.

I can apply vertical forces. Is some setting wrong? any idea how could I model this?
Any help is appreciated :)
Thank you
 
What are the error (and warning if relevant) messages ? Did you try with beam elements instead of T3D2 ?
Negative eigenvalues and zero pivot... I tried with other connectors as well. The MPC still gave me negative eigenvalues. I eventually solved it by deleting the truss element altogether and modeling the cable as one long connector element type axial :)
