Thanx for your answering so quickly.

I still have serveral qustions.
\"you might have to use /spawn to get back to the plaza\"
does it mean when I start the server , I must enter a command \"spawn hydlaa\"?

I orderly entered \"loadmap hydlaa\", \"spawn hydlaa\" and \"ready\", but still got the error message.

And I found there is a table called sector_info within the database, should I append a record for new sector \"hydlaa_plaza\"?

Yep, it\'s really a bit strange since I cannot find stoneb.spr at all, and this problem exists within some textures when loading the world file.

It raised underlying error when loading map podium:

I just wondering what and where these meshfacts are.
And as seen from the responses,  stoneb.spr was missing, but I searched entire directory, couldnot find this file, does anyone know where can I download it?

I complied the source code under windows and got everything ready to go. Then I launched the server and entered within the console \"loadmap hydlaa\", \"spawn hydlaa\", finally \"ready\". Everything looked pretty well here, but when I opened a client, trouble came, client side threw the following error:
\"The server could not create your player entity, please contact the tech staff.\"

and the server side also raised an error:

Check Login for: \'Roger\'
Guild info: Player is  (0) in guild  (0).

It seems that the server did really accept the account and just got the trouble at the stage of world loading. I tried several different accouts(including those initial acounts in the database), but failed to get rid of it.

Does anybody know how to solve this problem?

Thanks a lot in anticipation.
