Edit Orders v4.0 Support Thread

[Bonkycat]

Hello Diva,
Thank you for updating this add-on. I have only processed a couple of orders and already find myself in a bind needing to edit an order - and can't. I was thrilled to find this add-on and thought I was home free.... or not.
I am using v1.5.0 (php limitations won't allow update to v1.5.1)
It was a fresh install of this version
I added USPS RateV3 January 22, 2012 as instructed
I added group pricing per item (must have for me) via ftp
I have a template that I have heavily modified (appearance only)
I am hosted with godaddy (Linux)

My challenges:
My first concern was compatibility with group pricing. I have no idea how to compare/merge files if this is necessary, or how to find out if it is necessary.
Secondly - I read through your entire read me and I fear I can't use this add-on because of php? The read me says it is not compatible with any php prior to 5.2? I checked my hosting as instructed and it says php 5. I can only assume I am S.O.L because of the php version. Is this the case?

Thank you in advance for your time and any assistance you can offer.
