[Wien] mbj scf error

[Hajar Nejati]

dear Dr.Blaha

I performed your guidance step by step:First I did  "restore_lapw" the PBE calculation and run  ONE cycle using PBE. Then I switched to mBJ and did one cycle (-i 1). I did NOT get NaNs. 
 grep :DIS in case.scf :
:DIS  :  CHARGE DISTANCE       ( 0.1919842 for atom    1 spin 1)      0.1474900
:DIS  :  CHARGE DISTANCE       ( 0.1769903 for atom    1 spin 1)      0.1394753
Then I changed mixing in case.inm to PRATT  with mixing 0.03 and run mbj scf, but SECLR4 - Error appeared after 6 cycles.
Is there a key point that I didnot consider?! what is necessary to tell you for helping me?
