If you have access to the program that saved the EPS, try saving it out again, but as an older eps version. (if you have that option) Better yet, try saving an .AI file (again the oldest version your software will allow) and try importing it again.
If that does not work, chose the next oldest format your software will export. I believe that the eps2soft converter was written a long time ago, thus newer eps files are not compatible with it.
Hope this helps.
