I have a treo 600 that I bought off of Ebay that had documents to go loaded when I received it. (I'm not sure which version). I had to do a hard reset to fix a speaker problem and lost the documents to go application. The problem is that I didn't have the cd that the docs to go application was taken off of in order to put it back on my 600. I was told that I could use a treo 650 install cd which contains docs to go 7 and load it onto my 600. However,that didn't work. When I attempt to use word to go/sheet to go the screen says that docs to go 7 is not compatible with the 600. Is this because I took it off the 650 install cd? The only thing I can think to do now is buy docs to go 10 from the dataviz website. Any advice would be appreciated.
