deleting "All news" item in left pane results in error


System: Windows Vista Home Premium SP1, 2 GB, 32-bit
Feedreader 3.14

I imported a few news feeds (by prompt) when I first installed the program and decided later I didn't want an "All news" category. I clicked the item and pressed delete. I get the confirmation dialogue and after pressing "Yes" to "Do you really want to delete selected items?" I get an error message. Now I can't figure out if it's possible to ever remove that item. I tried reinstalling, but it remembers my history.

The error message says:
Title: Error
Body:
An error occured in program

Access violation at address 00645713 in module 'feedreader.exe'. Read of address 82D18419

After pressing okay the program seems to hang. I have a screenshot, if needed just send me an email.
