Stufflit Won't work after reinstall


Hi all i got problem that i don't understand. i've done a reinstall of the system since i had kernel panics. checked the disk with first aid. no problems. so i installed 10.2 over my current sys then downloaded the standalone updater files .1 .2 .3 .4 installed one after an other.

Now i download a file from the net (tried several from different sites). Stufflt starts and nothing happens.

i've deleted all the stufflt files and then reinstalled from a new copy (7.0.1).

And still nothing happens.

i checked the privileges with disk utility but that didn't help.

I don't know what to do anymore can someone help.
