Change date/time problem.

I am trying to move from 1.5 to 2.0 but I have a probem with the automatic update mode.
When I store the updated file I get the following log with 2.0
[18:28:13] Opening data connection to 81.21.75.160 Port: 4822
[18:28:13] STOR ReSeqFAQs.asp

Please can someone tell me what to do to prevent 2.0 trying to use MDTM.

Goto Settings->Transfer->Files and turn off "Keep File Time".

Many thanks - it's a pity SmartTP did not have notice of the default changes from 1.5 (or at least I con=ul not find it) nor was there any explanation of the function of Keep TIme
