sandyp_50, the upgrade to 2.400 was free to those who have 2.315. If you click your download link again, you will receive a new download file. This will LOOK LIKE it is 2.315 (in the filename) because our download software requires we use the same filename. However, it will download 2.400.
There are many upgrades and bug fixes along with a built-in ASPI driver in 2.400. It is superior and I recommend you download and use it. Using the most advanced and latest version in general is always the best idea. Bugs in prior versions are fixed in later versions. Thus, you won't run into problems in 2.400 that may appear in 2.315.
