Problems with May 2011 Version

Ever since I installed the May 2011 Version (previously I was using the one released in March) I get this blue screen "IRQL not less or equal" error and my system crashes.
I'm on a Intel Core 2 @ 2666Mhz, 2x2048Mb Ram (Kingston DDR2-333) and I'm using Windows XP Pro SP3.

Since the computer was out of shape for quite a long time, I decided to format it clean, in hope that the blue screen error would be somehow "fixed". Unfortunately even after the format I am getting the same error, which is linked to memory problems (as I found out through google)
I am currently running a Memory Test, to determine if there's something wrong with my memory (currently it's close to 50% testing, and no errors found yet)

Since I had no such problems with the earlier version of BCI2000 (March 2011) Is it possible to download an older version of BCI2000? and from where?

Thanks in advance,
Ioannis Karavasilis

Just a quick update to let you know that:
1.Memtest86+ (v4.20) found no problems in my system's memory
2. I installed the February 2011 Build, and everything's back to normal

Therefore I'm guessing I stumbled on a bug, which needs to get checked (I don't know if it's just me or other people using May2011 Version have been experiencing any similar problems)

Hi,

it would be useful to know which modules you are using, especially which source module/EEG amplifier.

Hi,

thanks a lot for your crash report. I identified a recent bug in the gUSBamp source module, and fixed it in SVN. If you want to try, you can compile the source module from the latest SVN version; if not, you may use the gUSBamp source module from the February build together with the current modules from the May build.

Best regards,
Juergen
