BPC NW 7.5 SP11: dump at refresh members

hi bpc gurus

Ps help me with this problem , i have BPC NW 7.5 SP11 (server and client , MS excel 2010 32 bits) and when I try to "maintain dimenssion members"on any dimenssion (entity for example) it dumps saying that on C:\...\Documents\PC_NW\DBW\Admin\myappset\AdminAPP\DimCache\Entity.csv is not found, when i check on windos explorer for DimCache carpet is totally empty.

I ve seen on TX UJFS comparing the AppShell (which i use to copy to my "myappset") vs IFRS (app set starter kit) , i see some differences:

As you can see on AppShell there is no xls files like the IFRS (app set starter kit), that could be the problem??

I also tried to refresh members and running program UJA_REFRESH_DIM_CACHE but the dump persists.

regards
