after installation (3 times - no change) i cannot unlock the system, cause some files are missing

. In the /status/htm/-folder i can see the files:
server.htm, storage-disk-0.htm, storage-disk-1.htm, storage.htm and syslog.htm.
when i use the linklist on the left (using a second machine and looking on the status-site) i have unusable links cause missing the files:
unlock.htm, about.htm, system.htm and network.htm.
how can i force the files are installed at setup? Is it possible to get these files and put them on the right place? Is my used .iso corrupt? Some ideas?
Thx for help
