Perl is slowly killing me!!

[zaljo01]

Hi Guys,
Trying to setup a new peq server, however having heaps of problems with perl.
I have installed activeperl 5.8.8.822 and when I try to load world.exe I am getting this error.
"The procedure entry point Perl_hv_common_key_len could not be located in the dynamic link library perl58.dll"

I have tried uninstalling, reinstalling, deleted perl folder and deleting perl58.dll.
I have also tried download perl 5.10 but getting perl58.dll missing files errors.

I have downlaod latest peqdatabase from svn and am using Vista 64bit.
I have had this working in the past with 64bit but am not having any luck atm.
Anyone got any ideas?
