Error: Downloading payment details

[ComicDomain]

Our host was recently involved in a malicious attack, at least thats what we've been told. Since then we've been unable to download customers payment details from our payment provider 'Worldpay'

The error message we get is this:

The web script was unable to open the specified file.

Possible Cause:
Permissions problems
The permissions on the acatalog directory are locked
The permissions on the file on the acatalog directory are locked
The path from the cgi-bin to acatalog directory is incorrect
or the directory has been renamed or removed
Recommendation:
Abort
Resolution:
Check the permissions of the web site.
The files and directories need to be readable
and writable by the web server
Run the Web | Configure Web Site Details command to
verify your setup

Command: retrieve Filename:

We've tried a full site refresh, but the error above remains - does anyone know if this is a Worldpay problem or a problem associated with our current hosts (Catalise)

Is anybody else experiencing problems with Worldpay lately?

We're using Actinic Business V7

Any details would be greatly appreciated - thanks in advance
