Modelsim SE code coverage error

Hi all.

I use modelsim SE 10.4c (not Altera edition).

I have a problem when use code coverage mode. Below i descript the problem:

I compile (using .do file) lot of sources:

vlog -work $prjworklib -novopt -lint -cover bcsxf +incdir+$incdir+$rtldir $rtldir/preprocess/filter/filter_mult.v
...
...

After this, i run the simulation from Modelsim console (using .do file):

vsim -L altera_mf -coverage $prjsimlib/work.tb
quietly WaveActivateNextPane {} 0
add wave -noupdate -divider {system}
add wave -noupdate -format Logic -radix unsigned {/tb/reset}
add wave -noupdate -format Logic -radix unsigned {/tb/sys_clk}
...
...
TreeUpdate 
update
run -all

Next, in modelsim i got coverage reports with some coverage results.

The problem:

When i try to open coveraged file using double click on non-coveraged code section or using file--open menu (see screenshot) - modelsim cannot open the file and i get error numeric coverage display disabled.
