Acronis TI 2009 on Windows xp x64 Pro - Major Problem

System specs:
Windows xp, x64 Professional operating system
Acronis 2009 True Image

Problem:
I had partitioned my hard drive, which is a Seagate Sata, 1.5 TB into 3 partitions (C, B, J)

My operating system was on C. Apparently I installed Acronis on B.

I was moving files to repartition the hard drive to expand my C Drive, as it was only 40 gb.

After moving some of my files from B and J, I restarted my computer and got: MBR 3 and MBR 1 error.

I did my research and found out that it was having trouble finding the boot file on my system, which must have been on the B drive.

I then downloaded and installed the file available in the forums to replace the boot record file, and now my system says it's unable to find my operating system.

I hooked my hard drive up externally and can't access it, but through Acronis I can access the partitions enough to see that the information is still there but can't/won't boot up. I figure that the boot file is for windows xp and not xp x64 and that is what the problem is. The loader installs files but has a couple errors that it can't seem to fix.

So, how and where do I get the boot file for my system? Also, if the boot file is missing, I figure that the whole Acronis folder is missing from my B drive and probably need the whole thing.

I had a thought that if I back up the system using acronis (which I can do having it hooked up externally) that I could possibly mount an old image and then restore newer files. I haven't backed up my system since last year, tsk, tsk on me. I have a big mess. My whole profession is on this computer and I fear losing files.

I don't have the original cd rom for my operating system because it is somewhere in storage from being in transition in moving, but I do have another version of windows that I could install if need be and as long as I can get all my files reloaded, mounted, or restored.

I've tried to be complete, but if you need more information or unclear about what I am saying please ask, I will be checking back often. Thanks so much for any help!!!
