Dell Warranty Info crashes

While running DellWarrantyInfo.exe (as elevated admin), it crashes with this backtrace:

C:\Program Files\Dell\Warranty>DellWarrantyInfo.exe get_info MyTags.csv config_f
ile=admin.cfg
OutputFormat : csv USER PREFERENCE read from the config file.
2756 Service Tags to Process.

It does not matter if I throw a file with 3000 or with 1 address at it... Tried through the proxy (normal setup) and as this crashed tried on a direct internet connection, to ensure the proxy won't cause any trouble.. same issue.

Any hints? The feature sounds like a great addition!
