Problems transferring contacts from Siemens CX75 to PC

I've tried many many ways, but still can't find the best solution to transfer contacts from Siemens CX75 over Bluetooth connection.

Mobile Phone Manager (Windows) from Siemens doesn't support Windows 7 and Vista. On Windows XP it has problems detecting the phone, but once it a while it can connect. The problem is that the phone gives error when trying to backup contacts with the Mobile Phone Manager or when trying to sync them.

XMPM (Linux) from BenQ-Siemens is hard to download. After long search I've managed to download the tar.gz archive with XMPM 1.3 from supposedly BenQ-Siemens FTP server:

ftp://217.21.255.101/mobile_phone/drivers/el71/xmpm_installer-1.3.06.34.0.tar.gz

The archive manager for Ubuntu can't unpack anything from it, while when unpacking with

tar xfzv xmpm_installer-1.3.06.34.0.tar.gz

I get the following error:

gzip: stdin: invalid compressed data--length error
tar: Child returned status 1

However most files are extracted properly and after replacing some lines, i.e.

1.

export PATH=$PATH:/usr/lib/jre-1.4.2_09/bin

onto

export PATH=$PATH:/usr/lib/jvm/java-6-sun-1.6.0.20/jre/bin

2.

echo "$version" | grep -q '1.4.2' &&

onto

echo "$version" | grep -q '1.6' &&

3.

export JAVA_HOME="$(cat $TMPFILE)";

onto

export JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.20";

I managed to start xmpm:

~/Downloads/XMPM_Installer-1.3.06.34.0$ sudo xmpm-service.sh start
~/Downloads/XMPM_Installer-1.3.06.34.0$ xmpm

The problem is that XMPM doesn't detect CX75.
