[Dx4win] Problem

[john paul]

I just got a message when I tried to log on using my DX4WIN
version 6.03.
The following message came up and keeps coming up
each time I try to open my logs.

DX4WIN V6
Access.Violation of Address 005B3E2A in module 'DX4WIN.EXE'
Read of Address FFFFFFFF

When I click OK
it shows this message
A fatal error occurred i reading the logfile.

When I click OK
on that one I get the following message
Unknown Version of Logfile.

How do I get this reset?

I am lost and can't find this in the help files.

Thanks
