Why can't I download the latest version of your software?
We occasionally get reports that a user cannot download the latest version of our software, and instead can only download a previous version. This is usually a problem related to caching.
A 'cache' (pronounced kash) is a collection of data duplicating original values stored elsewhere or computed earlier, where the original data are expensive (usually in terms of access time) to fetch or to compute, compared to reading the cache. Once the data is stored in the cache, future use can be made of it by accessing the cached copy rather than refreshing or recomputing the original data, so that the average access time is lower.
If you are experience a caching problem, clearing your browser cache will delete your temporary Internet files, and may allow you to download the file. Note that deleting your temporary Internet files may delete your browser history, though some browsers may have options to delete the former but not the latter. There are however no serious consequences of deleting your temporary Internet files.
Note: we no longer provide specific/detailed instructions on clearing browser caches, as the number of different browsers (and versions thereof) available means it would rapidly become out of date, adding to any confusion. You can probably get quick instructions how to do so by searching the internet itself (for example, searching on "clear firefox cache" gets numerous results). This article contains some examples, but we do not guarantee they will remain up-to-date. Remember that the results you get may not apply 100% to your version (number, 'model'). If in doubt, consult your browser documentation. Please do follow this suggestion if recommended; caching of old (and/or corrupted) content is more common that you might think.
If all else fails, try to download the file using a different computer or ISP as ISPs sometimes cache data in an attempt to save costs and/or improve apparent 'speed'. The problem with this practice by ISPs is that users do not download (are not supplied with) the most recent files, because the ISP intercepts the call to our website and silently delivers a copy of a (possibly older/corrupt) file of the same name from its own cache...
