Running GUIMiner/poclbm v2011-11-22 fine (20+Mh/s each on several GPUs) until Monday 12/22 and the application just stopped running on 3 systems simultaneously??!!??

Keep getting this error on all miners/systems:

Unexpected error:
2013-12-29 22:34:11: Listener for "user": Traceback (most recent call last):

2013-12-29 22:35:47: Listener for "user" shutting down

Any help?  A pointer to a topic I'm missing??

I suspect that maybe since mining difficulty has shifted to 1B+ that maybe there's something to the "...requires a string argument of length 32" error but I just don't have the knowledge to track down an answer.

I've looked for updated miners & gui's, searched The Bitcoin Forum, etc. and no answers.

Thanks in advance for replies.

Running MacPro G-4.1 on OSX 10.6.8 and GUIMiner/poclbm v2011-11-22 will not start mining with ATI Radeon HD 5770. No flags crashes & -v flag never connects to pool (BTCMP).

I suspect since this is an older OSX Machine & maybe mismatched GPU that maybe I'm missing a driver or firmware update for the ATI 5770.  Getting about 50Mh/s with ganged GeForce cards on seperate machines (prob losing $$$) but the ATI 5770 would triple capacity.  Still "dry-panning at Carbon Creek" but its something.  Any help greatly appreciated!

Of particular note in Thread 2 - "1   ...pple.ATIRadeonX3000GLDriver   0x000000010bce33d8 glrCompLoadBinary + 3560"  Maybe wrong driver?

Thanks in advance for any replies!!
