Thanks for your reply, and although I've had some help so far (Thanks to Andrey) I still can't install V2.0.5.
I have to say this Q&A style help system isn't as useful as a regular forum, and reading through some of the related posts to try and find similar problems and solutions only highlights that the original posters questions get quite fragmented into multiple questions. This makes it very hard to follow.
Having looked at V2.0.4 I can see the strengths of the CMS, but REALLY want to try V2.0.5+ as I will use the product for several projects.
I can't afford to spend much more time trying to get the product installed though (and from the tag cloud it looks like installation problems are the biggest issue with this CMS) so will have to look elsewhere next week if I can't get the thing working!!
I'm sat in front of my PC at work from 8-5 (UK time), trying to get this working for a good chunk of my day, so I'm available to respond to any help posted here. If there's anything else I can try or provide details of please let me know..
Many thanks,
Fred
