Using pep2 on HP running vista 64 bit with no problems until now. Just picked up tsu 9200 suppose to work on vista os. Put in install disc downloaded but pronto dashboard won't open up, did a little research found out not compatible with vista 64. uninstalled 9200. Now open pep2 and get "Pronto data service not running" error. The pep2 program takes longer to open than usual but does and now when I go to my database it's empty even phillips database empty. Just a hobbyist.
