Date time locale in AD audit Plus

Date time locale in AD audit Plus

I am trying to configure date time locale on our AD Audit plus (admin/personalize) but it only gives me Greek formatting options. I changed the server's regional settings from Greek to English UK but still no luck. The server is Windows 2012 R2 64 bit and AD audit plus is version 4.6.0 build 4685. All dates in Ad audit plus appear in Greek.  Any ideas?
