Hallo Herbert,
versuche es mal so - bei mir hat es funktioniert :-)

How to Update if after starting FontNavFix.msp it says that your serial is invalid:
1. Delete file DR13.dta in Dir [C:\Program Files\Corel\CorelDRAW Graphics Suite 13\Programs\]
2. Start CorelDRAW and use this serial: DR13WTX-0000046-GDR
3. Install SP2
4. Delete file DR13.dta now from 2 Dirs:
For Windows Vista (my case):
- [C:\Program Files\Corel\CorelDRAW Graphics Suite 13\Programs\]
- [C:\Users\All Users\Corel\CorelDRAW Graphics Suite 13\]
For WinXP (probably…):
- [C:\Program Files\Corel\CorelDRAW Graphics Suite 13\Programs\]
- [C:\Documents and Settings\All Users\Application Data\Corel\CorelDRAW Graphics Suite 13\]
5. Start CorelDRAW and register with any serial, generated by the SSG Keygen

Sp2 hast Du ja schon installiert, sonst wäre das zuerst - vor Fontnav-Hotfix - der gleiche Ablauf.

LG
