Patching error?Follow

OK After I downloaded the patch, I clicked the finished button. Then the updater minimized and stopped doing anything for about 3 minutes. I got anxious so I tried to log in but it said I still needed to download patch. When it got to the bnet updater, it displayed an error message that was like "Unable to write in the specified path."

I then went to my computer and clicked on the patch file and the bnet updater file, and all of a sudden, the Patch update finished screen showed up and I logged on.

Is it supposed to be like this?
