I have to reinstall the video drivers, or BOINC? Or both?
Thank for your answer.

I'd try BOINC first, try with version 6.5.0 though...
Although folks here in the forum may give you better idea on what client version is "safer".

i

6.5.0 is safer ...

I have seen reports of problems with all versions of 6.6.x; though some stay in a state of de-nile which can be hot this time of year... :)

Seriously, I have tried several and keep going back home ...

YMMV ... but if it screws up ... you been warned ... :)

I tried installing new drivers for my video card, and 6.6.22 version of BOINC... I'm crossing my fingers.

No, the problem is still here. I got almost the same error:

<core_client_version>6.6.24</core_client_version>

Have you tried BOINC client 6.5.0?
Because that would be the first difference with crunching for F@H...

This error usually pops up with an incompatible/or non-CUDA video card.

Now we're getting somewhere: your card is not recognized by BOINC and the recent 6.6.x clients changed their response to such a situation in that they'l try to run the app using the cpu emulation.

As mscharmack said it could be the driver. Under Vista the problem could also be that you installed (upgraded) BOINC as a service.. but you run XP home. Are you using remote desktop?
