help with cgminer error -61

I've reinstalled windows on this rig - the same version I had before (8.1) and now I am getting this "error -61: clCreateBuffer (padbuffer8), decrease TC or increase LG" about the maximum memory buffer
the thread-concurrency is set at 24000 (the same setting I used before reinstalling win and it worked perfectly fine)

details:
- rig has 2x 7950 with 8Gb of memory
- cgminer 3.7.2
- I am using the setx GPU_MAX_ALLOC_PERCENT 100 and GPU_USE_SYNC_OBJECTS 1
- AMD APP SDK 2.9 installed
- Catalyst 13.2 installed
- Win8.1 so it has .NET 4.5.1 installed
- I have rebooted the rig over and over again
- I've deleted the .bin files before each new try
- I've searched google like crazy for a solution and nothing there

I just can't figure out what's wrong with it, the exact same settings worked before and now they don't
Please help
