Instalation Fail

[Yorick Arens]

For so far he is installed but my ftp don't want to login.

Error filezilla:
Status: Verbindingspoging mislukt met "ECONNREFUSED - Connection refused by server".
Fout: Kan niet verbinden met server
Sorry it is Dutch

When I try to start the proftpd server the error is:
* Starting ftp server proftpd
- processing configuration directory '/etc/proftpd/ispcp'
- mod_dso/0.4: module 'mod_ctrls_admin.c' already loaded
- Fatal: LoadModule: error loading module 'mod_ctrls_admin.c': Operation not permitted on line 15 of '/etc/proftpd/modules.conf'
...fail!

How to solve this I just have followed the guide http://www.isp-control.net/documentation...tpd_issues
