Quote - Some are still in the store and I can't get them. This will determine if I purchase products from the vendors who do not reset the downloads for me in the furture.

The vendors don't control resets, those are done by the store staff. Where products are still in the store but not in your downloads, then the SNAFU must be something that only the RMP staff and/or programmers can sort out.

What can be awkward is vendor run promotions (e.g. a 2 for 1) where Renderosity can't do anything about the extra downloads that you might have got (because they weren't part of an order), those you have to rely on the relevant vendor(s) to replace.
