Change of mobo for sandy bridge, will it affect software use (CS5 master)

Question

Hello - new to this as you can tell from my question.
Just completed my new build, was very pleased with everything - system works a treat and about to purchase and intsall and register cs5 master this w/e
Realised may need to change mobo in April = advised by intel beacuse of sata2 controller problem with p67 chipset.I intend to replace mobo when corrected versions become available in April.
Question - my system disk is going to be the c300 ssd 128gb - it will contain - windows 7 ultimate, ms office, and cs5 master. When I change the mobo will my pc still work? Do i have to de register the software when i change mobo? or register it again?  Am I better of waiting til April before I install cs5 (though prefer not to). The components of my build will be the very same ones apart from the defective  mobo
I heard somewhere that I can legally use the software on 2 pc's though not at the same time. WIll I still be able to install and use it on my laptop if I need to, after I have changed the mobo in April.
(Also -- does anyone know the answers to the questions if for ms office.)
Thans for you help. I have not installed cs5 on a new build myself before, so really dont know what to expect after changing mobo

Answer 1

Well, I finally received my motherboard (Gigabyte P67A-UD7). Looks exactly like the old one, at least on casual inspection. Packaging is identical except for the graphics on the outer box. Only difference inside the box is that the SATA cables are black (first ones were blue). I'd forgotten how pretty these boards are- it was kinda cool to have two in the hand...
The switch was monkey-simple. I had to do one re-start, and since I added a few HDD's I had to change the boot order. (I know, this was a Very Bad Idea. Rule #3 is Never Upgrade More Than One Thing At A Time. But it was such a great opportunity to run more power cables and work on the cable management that I couldn't resist.)
Anyways, the software RAIDs were recognized, the drives were there, everything works the way it did and is absolutely fine: it even plays perfectly nicely with a couple of F2s that were a complete nightmare in my older system. 
In short, I checked the new and old boxes and got all the old packing together;
-took out the new board and took off the CPU cover;
-removed the GPU and cables from the old board and labelled them;
-removed the old board from the case, took off the cooler and cleaned it. Don't forget a bottle of 99% Isopropyl alcohol and a few pieces of gauze to clean the old thermal compound off the CPU and cooler.
-cleaned the cpu, removed it, put it in the new board, put on paste and reinstalled the cooler;
-packed up the old board and all accessories;
-did what i wanted to do in the case, reinstalled the board, hooked it up and reinstalled the video card.
(I probably missed some vital steps. This is not a guide, just a gentle encouragement to do it!)
I deactivated CS5 first using the total deactivation method so when I tried to open it I had to re-enter the serial number. Takes 5 seconds if you've already saved it to a text file- and I have.
I forgot to deactivate Lightroom and it didn't seem to make any difference, but I only have it on this machine. I would recommend deactivating first. Can't hurt and like Harm (and maybe others) said it takes seconds.
All in all, it was a totally painless experience (as these things go) and a great opportunity to do a few upgrades I'd been putting off.
