New order not showing (echeque)

[icklebits]

I have just received notification of a pending echeque but no order is showing up.

I see that on another thread its recommended to install a patch but I've never installed a patch before so do I have to install each and everyone of them in the thread that was linked to or just the last one??

Also will this make the missing order appear?

I need to know asap as I dont want to make a fool of myself when I email the customer saying "what did you order?". Not professional!

Thanks in advance.
