Converting from phpBB2 - error: Class 'phpBB2_000' not found

[محروم.كوم]

Hello all !

Today I were downloaded vBulletin 3.8.4 files and newest Impex. I've installed vBulletin correctly* and now i try to convert database.

All of impex files are on FTP* impex "works". ACP - Impex - Customer ID - Select systems. When I select system "phpBB2" and target vBulletin 3.7.* & 3.8.* and click "Begin import"* I've got error Code:
Fatal error: Class 'phpBB2_000' not found in /usr/home/fpg2/domains/cs-fpg.pl/public_html/impex/ImpExSession.php on line 114
Please* help.

EDIT: I have two licences for vBulletin. I have older impex (~month ago) on hdd* I unpacked it and look into phpBB2_000.php file.

In one (with error) I see modules for drupal! Code:
class drupal6_cms_000 extends ImpExModule
in older* in same line Code:
class phpBB2_000 extends ImpExModule

I've replaced phpBB2 folder from older package and all looks ok. So* this might be error in newest impex. __DEFINE_LIKE_SHARE__
