Hi,
There is a maintenance release of twlog - version 3.2
This version has been modified to compile cleanly on 64 bit as well as 32 bit systems. A script is included if you want to do a 32 bit compile on a 64 bit system, assuming you have the 32 bit libs.
Thanks to KD5COL for help finding a bug in the ADIF to twlog conversion code.
