Mistakes while update to VirtueMart 2.6.0a/2.6.1 from VM 2.0.18a

[borro]

Hello!

I was trying to migrate from VM 2.0.18a to VirtueMart 2.6.0a at localhost based at XAMPP 1.7.7(PHP 5.3.8 ) and after installation of aio packet i saw such messages:

•   JFolder: :delete: Path is not a folder. Path: some_path_prefix\administrator\components\com_virtuemart_allinone\languageBE
•   JFolder: :delete: Path is not a folder. Path: some_path_prefix\administrator\components\com_virtuemart_allinone\languageFE

After that these messages were displayed:

com_virtuemart_allinoneInstallerScript:: VirtueMart2 update #__virtuemart_payment_plg_standard
Table updated: Tablename ytgb1_virtuemart_payment_plg_standard dropped: 0 altered: 0 added: 1

Are these mistakes critical? Can i continue successful magration with these delete errors?

P.S. I tried to upgrade VM at newer XAMPP 1.8.2(PHP 5.4.27) - all the same...

The jfolder non exist I get everytime - may be fixed in 2.6.1  - try after this updating

the rest are success messages - so keep going

Thank you. After VM 2.6.1 installation I see the same error messages

annoying but not so important - I know the devs are heavily working on the Joomla 3.0 version which will be backward compatible to Joomla 2.5 so I'm sure this minor problem will be picked up in the stable vm3.0 release

thank you. Do you know is it normal to upgrade to VM 2.6.1 right from the VM 2.0.18a. May be it's better to use some intermediate version such as VM 2.0.26d for upgrade and then make upgrade to VM 2.6.1. What do you think about it?
I noticed that after VM2.0.18->VM2.0.26d->VM2.6.1 upgrade at the end there was a little bit less messages. Here they are:

JFolder: :delete: Path is not a folder. Path: some_local_path\administrator\components\com_virtuemart_allinone\languageBE
JFolder: :delete: Path is not a folder. Path: some_local_path\administrator\components\com_virtuemart_allinone\languageFE

I have never had problems with e.g. 2.0.18->2.6.0  etc
again messages apart from the language missing folder are all positive
