poclbm - out of host memory

[Deny]

After HDD crash and reinstalling the same copy of WinXp, .NET, 11.4 drivers and poclbm I see strange problem on well-working old mining hardware:

Exception in thread Thread-2:
Traceback (most recent call last):
  File "threading.pyo", line 525, in __bootstrap_inner
  File "threading.pyo", line 477, in run
  File "BitcoinMiner.pyo", line 277, in miningThread
RuntimeError: CommandQueue failed: out of host memory

Any ideas?
