execute in the current directory. you must be in the directory where you've stored the file. otherwise it won't work.
I'm definitely in the right directory as all other steps have worked. This is what i've done:
Code
pav@pav-desktop:~$ sudo upx -d DreamUP_Linux_1_3_beta

pav@pav-desktop:~$ sudo ./DreamUP_Linux_1_3_beta
sudo: unable to execute ./DreamUP_Linux_1_3_beta: No such file or directory
pav@pav-desktop:~$
Does that make it any clearer?
Thanks for your help
