Hi guys...I own L4 Platinum *with heaps of extras*...I see the extra functionality of L5 and looked at what it would cost...and it seemed that it was asking for $550 just to crossgrade. Am I missing something? I don't want to upgrade because I already own everything I would want in even portfolio, so I just would like to go from L4 platinum to L5 platinum. Is it really $550 or have I got it wrong? Thanks in advance for any light shed.
