Dont know if its a CM7 issue or just my phone, but I could until I flashed my most recent build 51. I tried to download 54 and it instantly fails. I tried to download something else and that failed too. My Handcent did just update through the market so it not a network issue. I have unknown sources on, if that even has anything to do with it and I use astro file manager to allow the browser downloads.
Is there somewhere else I could be looking for a setting that may not be checked? Like I sai it did work before I flashed 51. I also have Liberty toolbox, that just canged to ROM toolbox, installed too, but I dont really use it and it hasnt given me any problems with the other builds. Just though id put that out there though incase there is a setting in that that may be causing it too. Ive looked though and I cant find anything. I did restore from an earlier backup to see if it would help and it didnt, thats curious.
