How can i reinstall Thunderbird without losing mail and maps

[Longtallwally]

Who is possible to help me?
Since last week Thunderbird is not working anymore. I can not get connection with my netprovider. The adjustments are allright.
Is this a problem with my provider or Thunderbird?
Can it help when i reinstall Thunderbird but without losing mail and maps.

Reinstalling is very unlikely to fix a problem like this. I do need more information though.

* Which version of Thunderbird? Check Help>About for the version number.
* What operating system?
* What is the exact wording of the error message you are receiving?
* Do you have any extensions installed?
* What kind of mail - POP, IMAP?
* Is your mail service from an ISP, corporate e-mail system or Web-based?
* Are you using an antivirus and/or a firewall program? Which ones?
* Do you regularly compact your folders? Weekly or more often is strongly recommended. Check http://kb.mozillazine.org/Compacting_folders for more information on compacting folders.
* Without divulging your e-mail address or account name, what are your server settings, including server name and port number for:
+ Tools>Account Settings>*account*>Server Settings?
+ Tools>Account Settings>Outgoing Server (SMTP) (at the bottom of the list of accounts on the left)>*server*>Edit?
* Any recent changes in your computer or software configuration that might be relevant?
(including OS or Thunderbird updates, adding extensions or themes, etc. and any security program updates)
