Hi i was just wondering if anyone could help me with this. I bought a item on the marketplace and it did not get delivered. I then bought another item and that one did not get delivered. It then refunded my money and said 1 item failed with the error: Second Life communications timeout. I just bought 2 test items (freebies) and they got delivered no problem so i decided to buy the 500L$ item again and it wont deliver so i bought a 1L$ item and that don't get delivered either. It seems that if i order free items they get delivered right away but if i order something that costs money it does not. Any help would be great please as the item i want is not in store :(
