[AMBER] CUDA problems

CUDA was installed on my Linux workstation (which possesses two Nvidia GPUs) and it worked perfectly with Amber. Unfortunately, I mistakenly installed several recommended software updates, a number of which were for the Nvidia units, and now I can't get CUDA to work. Initially, the deviceQuery and bandwidthTest tests passed. Now they fail. The deviceQuery gives the following response:

Warning: Module nvidia_uvm_346.46 not found
cudaGetDeviceCount returned 30

? Unknown error
Result = FAIL

In my /var/lib/dkms directory I have the nvidia-uvm directory (note that this name is hyphenated, not underscored as it is in the deviceQuery error message). In /usr/src I have an nvidia-uvm-346.46 directory.

If someone could help me get past these problems and get my CUDA working again I would appreciate it greatly! I have found on the web that others have had this problem, but I haven't found a solution there.
