Unable to establish TM

Hello,

I am using Wordfast Pro and for some reason this message appears when I try to commit all segments to TM:

Unable to establish TM connection properly. The following error occured:
ABC.txt: Failed to connect. Translation memory header is invalid. Please note that this TM will be disabled.

Has any encountered this error previously and how can it be resolved?

Your assistance is much appreciated!
