Client error - downloading

I am running the beta version of Einstein for windows (0.03). I alos run setiathome. I am running BOINC 4.45.

I experience problems on downloading on a 56K dial-up link. Permanent, high speed connections from work operate flawlessly. While downloading an Einstein WU, Seti is downloading its WU's simultaneously, so they all go slow. While the approximately 7M eisnstein WU is down loading, multiple WU's appear for einstein in the "Work" tab of boinc. If there is a particularly slow download period, these WU's return a "Client Error Downloading" error (the last time it was thrre WUs that did it. This is very frustrating and generally results in my machine doing very little Einstein work while I am at home using the dila-up link.
Is there perhaps a later version of the Beta that fixes this?

(The Seti downloads seem to be far more tolerant and I do not get download errors on them)
