RevDrew -- Yep. I did that too and it worked for a bit and then stopped again. Ya know -- it's worth the 19 Euros to buy it as it does work beautifully and HaneWIN support was VERY responsive.
Leonardus -- despite comments made in some guides and websites, HaneWIN NFS DOES expire after the trial period and stops exporting shares -- at least with newer releases. The NFS services starts and then stops right away. You will see entries in your Windows APPLICATIONS Event Logs. Yuo will see a "Expired" message in the haneWIN app itself, but If you still wish to verify ...
1. Open a command prompt on the PC running HaneWIN NFS
2. Go to the PROGRAM FILES folder where haneWIN NFS is installed
3. from the prompt type "nfsd - debug"
If it has expired, you will see a nice little message.
