try this once... assuming it is a word, in corel convert to curves, then, with the word selected, use the 'break apart' (ctrl + k) command. select the letter(s), one at a time, that have an inside shape like an "O". Combine the shapes of that letter. Repeat. After all that, group all the letters of the word together, export as eps, and retry the import.
Oh, is this a font you imported / used before? I have had certain fonts do some really bizzarre (sp?) things in corel.
