Problems installing tar files

[adrian_fpd]

Hi guys
I have install on my lap debian 4.0 and in my house box debian 4.0 XFCE, the problem i have is when i m installing tar files on my home box it displays me and error message that in my lap does not.

pc-casa:/usr/local/src# tar -jxvf AdobeReader_esp-8.1.1-1.i.i486.tar.bz2
tar: AdobeReader_esp-8.1.1-1.i.i486.tar.bz2: No se puede open: No existe el fich ero o el directorio
tar: El error no es recuperable: salida ahora
tar: Child returned status 2
tar: Salida con error demorada desde errores anteriores
pc-casa:/usr/local/src#

i installed other programs and still show me the same error, all the software work on my lap but on my box does not
I know that i can install software on different ways using apt-get dpkg ... etc
but i really want to know what s going on in my box

AdobeReader_esp-8.1.1-1.i.i486.tar.bz2

Are you sure it isn't AdobeReader_esp-8.1.1-1.i486.tar.bz2?
