Annoying lines in AI

hi

i just tried to export a logo from corel draw to AI, but AI has added some really weird lines over the whole logo, rendering the whole logo quite useless because it also adds all of the effects on these excessive and annoying lines...

the logo basically uses some round and straight lines and the weird lines have been added into all of the openings of the top layer of the logo...

so how can i get rid of these annoying lines? maybe need to delete some nodes in corel draw? but how can i then combine different lines to get my end result that works everywhere else, except AI?

thanks

well.. i now got rid of the annoying lines by connecting all of the weird arrows into nodes in corel, but now i have a white square over the whole logo in AI... is that normal?

Copy your logo select by mouse and then paste you logo to Adobe illustrator. save AI format.

I have also creating this type issue on it. How can I do it ?
