Since end of February I have many calculation errors (more than 50%).
The error code is always:
core_client_version>6.6.11</core_client_version>

I´m using:
Processor: 4 GenuineIntel Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz
Processor features: fpu tsc pae nx sse sse2 pni
Microsoft Windows Vista: Ultimate x64 Editon, Service Pack 1, (06.00.6001.00)
Memory: 4.00 GB physical, 8.17 GB virtual
Disk: 931.50 GB total, 652.09 GB free
CUDA device: GeForce GTX 280 (driver version 18208, CUDA version 1.3, 1024MB, est. 111GFLOPS)

Updating of nvidia-driver was without any luck.

Any Ideas??
Thanks in advance.

Your GPU shader clock is 1.50 GHz, whereas the stock setting is 1.30 GHz. Lower your shader clock to maybe 1.40 GHz and, if the core is OC'ed as well, lower that one by ~50 MHz and see if it helps.

Did you change anything? Did you reboot the machine and/or power it off for >10 mins with removed power cord?

Will buy a new graphic card LOL

Will buy a new graphic card LOL

Well, if that's funny for you go ahead ;)

Otherwise there are a couple of things to check:
- did you change anything, hard- or software wise?
- did the GPU fan fail? What's the GPU temperature under GPU-Grid? (Everest or GPU-Z can read that out)
- does it help if you underclock a bit? (~100 MHz shader and ~50MHz GPU core)
- can it still run 3D Mark in a loop for >1 hour?

If you want to get a faster card anyway this won't matter much. But if you want to know if you can throw the old card away or reuse it in an office computer it might be good to invest some time into checking it.
