Version compatibility in forms generated with Adobe Designer 7.1

i have developed form using adobe livecycle designer 7.1.
first, saved "acrobat 7.0.5 dynamic pdf form file" and, when tried open acrobat reader 7.0.3, crashed.

then, saved "acrobat 7.0 compatible pdf form file" , tried again open acrobat reader 7.0.3. unfortunately, crashed again.

has experienced similar situation? or know way overcome it?
any comments appreciated.
thanks in advance.

are opening them on same machine? find when have acrobat 7 , designer 7.1 open on same computer both become unstable. when close acrobat , work in designer alone can work hours no problems. reader 7 on other machines has no problem reading pdfs.
