After I unrar the driver download i try to use make which gives me this

Code:
make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/3.7-trunk-amd64/build M=/engeniusdriver  modules
make[1]: Entering directory `/usr/src/linux-headers-3.7-trunk-amd64'
make[4]: *** /usr/src/linux-headers-3.7-trunk-common/config: Is a directory.  Stop.
make[3]: *** [_module_/engeniusdriver] Error 2
make[2]: *** [sub-make] Error 2
make[1]: *** [all] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-3.7-trunk-amd64'
make: *** [modules] Error 2
I would appreciate any help!
