Do any of the updates for FileMaker 5.5 apply to 5.5 Unlimited?

Should I use the FileMaker Pro 5.5v2 updater on my FileMaker 5.5 Unlimited? Should I use the FileMaker Pro 5.5v3 Web Companion updater on my FileMaker Pro 5.5 Unlimited Web Companion?

I'm attempting to run FileMaker Pro 5.5 Unlimited on Windows 2000 Professional. My server is a G4 running OSX (10.0.4 client) with FileMaker Server 5.5

I'm experiencing many problems. My system works great and has for about a year now with FileMaker Server 5.5 on the server and FileMaker 5 Unlimited on my Windows 2000 machine. As soon as I update the Unlimited 5 to 5.5 on the Windows 2000 machine, Unlimited just stops working every few hours.

I have spent several hours rebuilding older data bases to see if that would solve the problem but it made no difference.

At this point, I put FileMaker 5 Unlimited back on my Windows 2000 machine until I can find a solution.

Anyone have any solutions, please reply.

Thanks
