Hi Liwei,
I had this problem, that you mentioned, in the process of finding a workaround as well. I guess both issues are due to wrong access authorization of the memory.
I would rather recommend (as also Georg did) using batch-scripts instead of the GUI. What helped me was using the test data provided by martin (Building LCModel - #2 by admin) to get used to the syntax of the control file.
I hope that you can fix your problems with this!
Best
Fabian
