It is recommended to upgrade step-wise from version via next version(s) except between LTS versions. So from 12.04 LTS you will be able to upgrade to 14.04 LTS in the end of April (or better beginning of May, when the worst bug are squashed). Otherwise upgrade in a chain

12.04 LTS - 12.10 - 13.04 -13.10

which is a long chain prone to breakage. But skipping 12.10 a dn 13.04 might have caused your problem, and other problems might be lurking.

Maybe the best thing would be to copy your home directory to an own partition and let it be a home partition, and reinstall 13.10 (with separate root and home partitions).
