We bought our premium license last year and it was due to expire on 10/28/09 (version 3.51.13). We just bought another one and this time it expires in 9/3/10.
A license is valid for one year (your old license is still valid for 7 weeks so there was no need to purchase a new one at this time) The license date is calculated from the moment you purchase (pay) the yearly fee.
Please mail us at lansweeper@hemoco.com so we can try to correct this.
