How do i use the sizing feature? want to go above 100% which is available on upgrade 1

Hi Annie, It all has to do with your foot pedal. CHECK to make sure it's plugged into your machine properly.
IF it jiggles around in the socket, wrap a bit of tape around the rubber/plastic part that goes into the socket. I had to do that with one of my machines about a month after I got it...that was 10 years ago, still works great.
If these things don't work, then you may need a new foot pedal, or a new socket...or both.

THE link below will take you right to the page in the manual that explains the error. I hope the tape works for you:)

Singer has the manual for the Futura XL400 on the product site: http://www.singerco.com/products/2168/xl-400-futura . The direct link to the instruction manual is http://www.singerco.com/uploads/download/bbd749beb7151a637824d777a05c51b4fb50b0a4.pdf . There is also a quick start guide. Additional documentation and driver upgrade software is here: http://futura-support.com/products/xl-400 . Unfortunately, Singer doesn't provide replacement CDs if you lost the original one. According to the directions for the driver upgrade, you need the CD to install the upgrade.

The software packages are available for sale at Amazon and other vendors. Some CDs may be available on E-bay.

I hope the manual helps.

You might check out some of the older Bernina manuals to get an idea of how it may work in your machine. The 1260 is the closest manual available. Looks like your machine takes the same push-in bulb. So, you would push up on the bulb and twist. Then you would install the replacement the same way. Sometimes, using tight fitting medical gloves helps grip the bulb in order to twist.

BERNINA Sewing Systems

BTW--I have older Berninas and upgraded their bulbs to LED.

Unfortunately, I don't know of any free sources of the manual. It is available here: http://www.sewingmanuals.com/Sewing_Machine_Manuals/Viking.htm . Scroll down to the 64th item in the list. You can also check with a Husqvarna Viking sewing machine dealer in your area.

I hope this helps.

(I know that many dealers can get the manual for you. I was able to get a manual for an older Bernina serger for a minimal fee a few years ago.)

This is only available through an authorized singer dealer. Where To Buy Singer Products Singer Sewing and then do the update here CE 100 Software

Only if the machine was upgraded to USB. Then, a new version of disk manager came with the upgrade kit that your dealer installed.Otherwise, it comes with any of the 5D Embroidery packages that are currently available.

No it's not, All Singer futura users should be intitled to a 100% refund, or Singer should install new chips in the c-100's for former users. This is obsurb! you invest in the machine, and when the software upgrades itself, you are unable to use your machine. This is so awful

If you have upgraded to Vista, there have been considerable troubles with all makes of machine in the last few years.
You will probably need to find an upgrade to the software (generally free), so contact Singer in your region.
Here is their Global Site Link if you need to find a contact locally to discuss your needs.

most commonly this is from incorrect threading top thread. Check manual for threading path or follow threading path usually marked by arrows on machine
