scanning warning ???

Hi,
Perhaps this is a known problem …
When “Copernic Tracker” is tracking I get following error msg for every folder data file:
"AAVM - scanning warning: x_AavmCheckFileDirectEx [UNI]: E:.…\APPLICATION DATA\COPERNIC\TRACKER\DATA\JAVA\MAILING LISTS\FOLDERDATA.DAT returning error, 0000A477. "
Can someone help?
TIA
Willy
