Downgrading Hoster

[Lloyd Te Kani]

Hi everyone. I had a "man's look" for a previous thread relating to this issue but couldn't find one so here goes.

My "show laptop" has 1 gb of ram and has been operating with little fuss even with Hoster 4.11. My back-up desktop has 3 gb of ram and operates flawlessly with the same package. Anyhoo, forgetting for a moment the ram question, I decided to download 4.20 on to my desktop having been suitably impressed with the new features. All good until I realised my laptops limitations ram-wise. I also purchased a second identical laptop at an "offer I couldn't refuse" which I intend to use as my back-up, yes, with identical ram capacity.

Question one, can I downgrade Hoster (bearing in mind the ram issue) and secondly which version would be best for me using Windows 7?

In your responses, please try and overlook my lack of foresight.
