[TYPO3-english] te_openemm_newsletter installation problem

[Gerber Daniel]

Hi,
Sorry if this message is in the wrong list, not really sure... (usually I'm writing to the dev lists :-). I'm trying to install the te_openemm_newsletter extension for the OpenEMM Tool [1]. But after installing OpenEMM and all other dependencies something goes wrong. After importing the extension this happens:

Extension imported
Folder created: C:/xampp/htdocs/typo3_lsm1/typo3conf/ext/te_openemm_newsletter/
TYPO3_MOD_PATH and $BACK_PATH were updated in "typo3conf/ext/te_openemm_newsletter/mod1/conf.php"!
TYPO3_MOD_PATH and $BACK_PATH were updated in "typo3conf/ext/te_openemm_newsletter/mod2/conf.php"!
TYPO3_MOD_PATH and $BACK_PATH were updated in "typo3conf/ext/te_openemm_newsletter/mod3/conf.php"!
TYPO3_MOD_PATH and $BACK_PATH were updated in "typo3conf/ext/te_openemm_newsletter/mod4/conf.php"!
ext_emconf.php: C:/xampp/htdocs/typo3_lsm1/typo3conf/ext/te_openemm_newsletter/ext_emconf.php
Installation Type: Local

Which seems all right, I guess. But If I click "install extension" this happens:

BadFunctionCallException TYPO3 Fatal Error: Extension key "te_openemm_newsletter" was NOT loaded!

The protocol admin tool says the following:

Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1270853878: TYPO3 Fatal Error: Extension key "te_openemm_newsletter" was NOT loaded! | BadFunctionCallException thrown in file C:\xampp\htdocs\typo3_lsm1\t3lib\class.t3lib_extmgm.php in line 156... the corresponding lines in the t3lib_extmgm.php suggest that the key was not set in the global array of extensions?!

	public static function extPath($key, $script = '') {
		global $TYPO3_LOADED_EXT;
		if (!isset($TYPO3_LOADED_EXT[$key])) {
			throw new BadFunctionCallException(
				'TYPO3 Fatal Error: Extension key "'.$key.'" was NOT loaded!',
				1270853878
			);
		}
		return PATH_site.$TYPO3_LOADED_EXT[$key]['siteRelPath'].$script;
	}

Any ideas on how to solve this issue? I would really appreciate any sort of help!

Kind regards,
Daniel
