My pc crashed, updon reboot I'm unable to run PSCS6 lens correction filter. The error reads "The end of data was reached while reading from a container". The crash occurred while using the lens correction filter, the pc locked up. When I rebooted everything worked fine except the lens correction filter.
Sounds like one of the cache or preferences files for that plugin got corrupted when you rebooted.
Now, the machine locking up is another issue - that can only happen due to hardware faults, OS bugs, or low level driver faults.
If that happens again, you need to check your system for defective hardware (bad RAM is the most common cause, followed by GPU, VRAM, CPU, motherboard and power supply).
