...a week ago I have downloaded WebSite X5 Compact 10 ...and tried to work following the tutorial instructions... it did not work...then I realized that the tutorial refers to WebSite X5 Evolution 10 (i like the tutorial)...to upgrade I had to purchase the new program...now I have downloded two similar programs...however, neither one works. WebSite X5 Compact 10 can not run because original serial number does not work since program was updated. WebSite X5 Evolution during downloding had been interrupted by some error and I can not download or run this program again...what I should do?
