Removing versionhistory entries from SQL

Aloha,

We are having a problem installing a third party addin (RMSify). The install fails as it is checking the current version in the versionhistory table. MaxVersion in that table is returning 3.01. When in fact the database is at version 2.05. Assuming we have no other third party addins (which I am mostly confident we do not), is there any danger in deleting all version entries except 2.05 (where we currently are, based on Operations Administrator)?

The queries I am running are

To obtain the current version:

select max(version) from versionhistory

And to remove older entries from that table:

delete from versionhistory where version='3.01'

Any insight would be greatly appreciated.
