Hey APer's I'm suddenly having a constant error message in CS4.

"Trouble reading or writing to scratch disk error -36. Error is unrecoverable."
it then shuts itself down. Never had this problem before

this happens when I try to use the Distortion filter to correct lens distortion( other filters work OK) and when saving a file.


my selected scratch disk is my E drive which has 274 GB free
XP SP3 2 GB RAM
Any one got any ideas?
