To learn how to mesa, I suggest studying relevant examples in the test_suite.  

For  the current problem you mention, get started by

cd star/test_suite
grep 'create_pre_main_sequence_model = .true.' */inlist*

That will give a list including these:
150M_z1m4_pre_ms_to_collapse/inlist_150M_create_start_model:      create_pre_main_sequence_model = .true.
1M_pre_ms_to_wd/inlist_1.0:      create_pre_main_sequence_model = .true.
7M_prems_to_AGB/inlist_7M_prems_to_AGB:      create_pre_main_sequence_model = .true.
cool_brown_dwarf/inlist_cool_brown_dwarf:      create_pre_main_sequence_model = .true.
example_astero/inlist_1:      create_pre_main_sequence_model = .true.
make_he_wd/inlist_wd1:      create_pre_main_sequence_model = .true.
make_metals/inlist_make_metals:      create_pre_main_sequence_model = .true.
massive_rotating/inlist_pre_ms_massive_rotating:      create_pre_main_sequence_model = .true.

So now you have 8 example tests that do create pre-ms models.  Look at them, run them, and see if that helps you.
