ErrorUpon opening RivEX you are told that it unable to LOAD the RivEX license file. 

SolutionThe RivEX license file (RivEX_License.rlf) is located in the folder C:\RivEX\License but there should also be the accompanying  RivEX_License.dtd file. If this is missing then RivEX is unable to read the license file. If you have deleted it by mistake then restore it either from the Recycling bin or the original zip file you downloaded when you purchased RivEX. Failing that you can contact me.
