UGS Errors when converting files to G Code

[Rick23n]

My Laser is working fine now apart from the misrepresentation of power by the seller but the program is working fine. I have since replaced the laser with a cnc router and can engrave with it using an online text to cnc where the g-code is generated directly on their website. That's all ok unless you want to engrave an image. They will do it for a cost but it can also be done using Inkscape and creating the g code for UGS. That's where the problem comes in. Following the guidelines explicitly and converting a "bmp" file to a "svg" file and trying to open that file in UGS I get the error "Problem opening file: Multiple S-codes on one line" I have researched as much as I can but it seems other people also have the same problem and no solution. It is so frustrating. I hope someone can help me.
Cheers Rick
