just follow the clues in the wizard mode;
it isn't difficult, but using russian software without a bought (but although accepted) key is a real risk;

Powerquest PartitionMagic seems to be more tolerant in such cases;
before changing partitions make a (ghost) image to another HDD or to approximately 50 CDR;

behind the existing one;
and btw "CDR/RW Software" seems not to be the right rubric for this;
