Did you try to open it with another program (such as Wilcom TruSizer, which is a free download), and then re-save it as a different name. I have found some designs files will work properly for me after re-saving it. Good luck!

first thought http://www.geothedigitizer.com/ but is is not, sorry

I have never seen it before, so I think it is from long ago. I really like it, if you do find it again, can you please let me know! Thanks

What is the file extension?

Sometimes my 4D software does not like a design but Wilcom or Stitch Era or Bernina Artlink will open and save it and then it opens ok in 4D. Also sometimes there is a comma or other symbol in the name that is stopping the design from begin recognized. It is a neat looking design, hope you can make it work for you.

Have you tried to convert it to another format then resize, then reconvert?

This has happen to me with another design.I have embird. It was suggected that i check the hoop size.I did that by ticking the hoop size again and then the design worked. Hope this make sence and it may help. Good luck

With those outlines, I also thought maybe George the digitizer, but the other option might be the site that closed, Got A Stitch? Which would be of no help to you, sorry! Ramon of Embroiders Eye did some Muscle Cars at one point, but I didn't manage to find those, however I don't think this one looks like his style. Best of luck finding it -or enlarging it.

Thank you all the cuties for your suggestions.
I first downloaded the Wilcon TruSizer but when it was a bugger to work on I went to Embird and saved the pes design in XXX format and it resized to 150% without problems!! So now I can work on and fix the stitching.
Again, many thanks to all!!

So happy that you got it worked out and thanks for letting us know.
