Blank page after trying to update to 2.0.22c

[micropalla]

Hello.
I've Joomla 1.5 and I've performed a migration from VM 1.1.9 to VM 2.0.
Everything was ok.

After I setted my shop I tried to perform the update to version 2.0.22c.
The installation was ok but now when i try to access to the administration page i receive a blank page.

What can be happened?

VM2.0.22 is not compatible with Joomla 1.5, you should migrate to Joomla 2.5

Joomla 1.5 is no longer supported.  http://virtuemart.net/news/list-all-news/426-end-of-life-for-virtuemart-11-heidelpay-now-in-virtuemart-2012

If I perform a migration now to J 2.5 you think the problem will solve?

I think it was mentioned very clear by Jenkinhill.
