In order to see the problem I suggest adding the 'debug' option to ppp/pptp, you can do this on the client by adding debug to the pptp command. You can also add the debug option on the pptpd server in the pptpd.conf file.
You need to have the ip_gre module in the kernel, the pptp communication of the LCP packets is also in the GRE channel. Make sure both sides have the module loaded. Make sure you don't have a firewall blocking the gre packets from arriving to either side, a fascist firewall may need an extra rule for this. If it still doesn't work send the log of the pptp and ppp (both of them with debug).
