Hello Panda people, I could use some help please.

About a month ago I was having problems receiving the latest blocks and I was told to fix this by switching to classic mode and waiting for the update (v3.0.1) which had fixed the problem but a couple of days ago the problem returned once again and last night I switched back to classic mode. This morning when I turned my PC back on I got an error saying "Error loading blkindex.dat" and when I click "ok" Pandabank closes and I get the same thing if I start it up again.

Also just as a side note while I am posting here. Despite being told a month ago that the annoying update messages would soon disappear they never did for me. Maybe this problem is related, maybe not but thought it would be worth mentioning.

Thanks
