Creep - using Beams

Working in Ansys Workbench, I have a simple line geometry which I given a rectangular cross section to model a simple tensile creep sample. In mechanical I have 2 time steps with Creep off for the first and On for the second. The software does not offer me the Creep Strain output in the Solution. I have checked the APDL element reference and it says that beam element 188 can be used for CREEP................. am I missing something here?

The model also doesn't want to converge on the 2nd time steps ... it says

Equivalent creep strain ratio has exceeded the specified limit value.   Since the time increment has reached the minimum value, the analysis  is stopped.
