Query: Product Works Erratically and Tech Support is Poor

I installed this product in early February and have been fighting to get it to sync my e-mail from Lotus Notes 4.5 ever since. The calendar syncs fine, but the software terminates every time during the e-mail sync and nothing transfers. I have reinstalled both the Intellisync and Palm applications, had my drives and network profiles reinstalled, and configured Intellisync every way under the sun. Pumatech tech support gave me a few suggestions, none of which worked. When I called back, they wanted me to buy a "tech support ticket" for $19.95 because my 30 day free tech support warranty was expired!I'm not wasting any more time or money on this product. I'll switch to something that works.
