Currently happening in MFN 6.

Yes, someone pm'ed me yesterday saying he couldn't trade with me due to this error message.

I tried to make trade offers to about 10 different teams yesterday and I got this message with about 5 of the teams. I suppose it's possible that all 6 of us are on a common IP...but it seems unlikely.

I have a feeling there is a conflict to people using the old / new interface

Possibly, but I try to make the trade in both versions and got the message in both.

Ah right, blows that theory up then

I actually think you might be right, a conflict if both parties have accessed both versions. I think I've fixed the corrupt records.

I'm still getting the "unable to process" message in CUST-35.

happened where people couldn't trade with me the other day what it was is i have an account under 30 days old so if i list a player on trading block with new interface, try to initiate a trade with the new interface or someone sends me a trade using the new interface the trade will not go through

if trading to or from an account under 30 days old you MUST use the old interface

I just had a trade offer to me that showed that the other owner had an advantage in the trade, I rejected and went to counter it and when I was in the other screen before making any adjustments it showed the trade to be in my favor.
