Going crazy...

Had some problems while uploading logos (some of them were rejected because of the corrupt .eps file). And I've decided to download Corel Draw X6, and I was really puzzled that .SVG files I made in Inkscape look so strange and... well, I tried opening some of the .EPS versions of the logo, it opened in Serif X4 DrawPlus (no problems - logo looks good without any bugs), than I opened it in Corel - it showed an error. That's really crazy! Whats that? Is it a war between graphic editors? Look yourself... I really don't want to experiment with Corel Draw after all, it even cant open .SVG normally, and that is...
